Demon (February 13th 1866, Bracken County, Kentucky)

On Monday night the owner of a local plantation and his family had retired to rest when suddenly they were aroused by a great outcry from the 'Negro' quarters, which was immediately to the rear of the house. They heard men, women and children screaming in terror, creating a scene of utter pandemonium. His wife and him sprang from their bed. Their room was illuminated as brightly as by a flood of sunlight, though the light was of a bluish cast. At first they thought that the 'Negro' cabins were being consumed by fire. They rushed to the windows and beheld a sight that fairly curdled the blood in their veins with horror and filled their hearts with utmost terror. Their daughters, shrieking loudly, came flying into the room, hysterical with fear. They beheld, standing to the right of the upper cabin, near the fence that separated the 'Negro’s' garden from the house yard a creature of gigantic stature, and the most horrifying appearance. It was nearly as high as the cabin and had a monstrous head not similar in shape to that of an ape, with two short white horns above each eye, and it had long arms, covered with shaggy hair of an ashen hue that terminated in huge paws, not unlike those of a cat, and armed with huge and hooked claws. Its breast was as broad as that of a large sized ox, its legs resembled the front legs of a horse, and only the hoofs were cloven. It had a long tail armed with a dart shaped horn, which it was continually switching about. Its eyes glowed like two living coals of fire, while its nostrils and mouth were emitting sheets of blue colored flame, with a hissing sound, like the hissing of a serpent only a thousand fold louder. Its general color, save the arms, was a dull dingy brown. The air was powerfully impregnated with a smell of burning sulfur. The poor 'Negroes' were evidently laboring under extreme terror, and two of them, an old woman and a lad were actually driven to insanity by their fears and have not recovered their reason up to this writing. The strange creature then was enveloped in a spiral in a spiral column of flame that reached nearly to the top of the locust trees adjacent, and which hid its horrid form completely from view. The extinction of the flame was instantaneous, and with its disappearance they were relieved of the presence of this remarkable visitor. It was reported that the same or similar creature appeared on several nights at neighboring plantations.

Green Dwarf (Winter 1959, Derry, New Hampshire)

The witness was gathering Christmas trees when he encountered this ostensibly alien entity. It did not look very human, and had a high domed forehead with green and wrinkled skin. In place of an external nose, it simply had holes and it had green 'glossy' dorsal spines as well as greyish-green body hair. The feet and hands of the creature were described as being 'like stumps', and so it would be reasonable to suspect that they lacked digits. The creature sounds extremely similar to the legendary Chupacabra from this description - not to mention the fact that this thing could literally be described as a 'little green man'.

Ufonaut (26 Nov 1972, Zamora, California, USA)

Driving home from her grandmother’s at Bodega Bay, to Zamora, with her two younger sisters, Judy Kendall, 28, expected to be home at approximately 2000. She in fact got home about midnight, finding her parents alarmed over her lateness. She recalled having crossed over Cache Creek Bridge about 2000, and then crossing over it a second time, feeling very tired and barely able to keep her eyes open. Under hypnotic regression, she described feeling an extreme coldness, and of a void around the car; she believed she was floated out of the car and awakened in a round room encircled with windows through which she saw stars. She was on a hard cold surface, and her head seemed to be restrained at times, prohibiting movement. She was able to observe, with restraints removed, two-bucket seats facing a console type instrument panel with a gear like shift; and on her left a table with instruments and a black box. The feeling of cold was intense.
Present were five entities of frightening appearance; with insect like eyes and a pale, or white translucent skin through which was visible a number of red veins. They wore an outfit with a turtleneck top that apparently concealed the lower portion of their faces. She is told that no harm will come to her but the voice does not appear to be spoken normally, sounding more like it came through a megaphone. Three other entities are dressed in similar outfits but apparently lack the bug like eyes of the first. The fifth is an entirely human appearing woman with blue eyes and long black hair, who speaks to her normally, and calms her. She was given an examination, which, she believes, included catheterization; she felt “shaky” experienced pain in her head, and a pain in her side. At times she experienced some difficulty in breathing. She expressed concern about her sisters, one of whom she believed she heard calling out to her in distress. She was not certain that both sisters were brought on board with her. Her feet were examined closely and at one point during the examination, one hand, or arm, was restrained so that she could not move it. The sensation of cold was relieved briefly several times, but severe headaches persisted throughout. Finally a large “scanning” device was placed over her face, and she was unable to see; it gave off a motor sound and when removed, she was again able to see. She was then carried out of the room and next thing she recalled was being “thrown” into the driver’s seat of the car, and her sister was suddenly in the seat next to her. She felt very tired and recalled crossing the bridge for the second time, after which she and her sisters proceeded straight home, arriving four hours later than expected.

Deer Man (2012, Wichita Mountains, Oklahoma)

Kyle Heying claims that he was out at the Wichita Mountains National Wildlife Refuge in order to take photographs of the night sky there with a friend. On this evening at around 10 PM, the usual sounds of the forest suddenly became muted and the local wildlife started to display some decidedly bizarre and uncharacteristic behaviour. First some elk came running by and then a herd of bison, which all came uncomfortably close before hurrying off, and it seemed almost as if these animals were trying to get away from something scaring them out in the dark forest beyond.
This was enough to spook the men into packing up their stuff and calling it a night, and as they did they allegedly felt a strange change in air pressure and all of the sounds of the woods just stopped to send a profound silence crashing down upon them. The two unsettled men then heard something rustling about out in some tall grass nearby, jarring in the otherwise void of silence that had blanketed the area, and it seemed like whatever it was was coming towards them. Heying claims that he and his friends had then picked up some rifles they had with them, wary of what was apparently approaching. They started the car and began to drive off when they saw something step out in front of the vehicle that they would never forget, a creature which Heying described as having a head like an elk but which stood upright on two human legs and which had two human arms and “dark red” eyes. As they passed it, the nightmarish creature lurched forward to hit the car, and Heying floored it away as fast as the vehicle would go until they were about 3 miles away, where they stopped their flight to regain their wits. Heying would say of what happened next thus:
“We were scared shitless. Things got even quieter when we stayed there. While there we heard one ear-piercing screech or scream, almost a hunting screech of some sort that made my hair stand on end and gave me goose bumps even worse. With that we left the mountains completely, we felt as though we were not wanted there that night. The way the wildlife acted, the figure that we came across that the animals had to have ran from, and then the scream of which I can only find references to happens to be the Banshee. I cannot forget that figure we saw, as well as the scream. It was not human but it was not of any wildlife I am familiar with from out there.”

Mineral Point Vampire (1981 - 2004, Mineral Point, Wisconsin)

On the evening of March 14, 1981 there were reports of a vampire-like figure lurking in Graceland cemetery. The police responded. At the cemetery, a lone officer confronted a tall, thin, pale faced figure dressed in black and wearing a cape. The figure suddenly bolted. The officer gave chase. The chase ended when the pale man lept over a six foot fence at the border of the cemetery. The next morning, the police returned to the cemetery to follow tracks made in the snow. At the point where the pale man jumped over the fence, his tracks disappeared – there was nothing but untouched snow on the other side of the fence. In March, 2004, police responded to reports of man sitting in a tree outside of an apartment complex. When they arrived, a tall, thin, darkly clad man with a pale face leapt from the tree and fled. The police followed but quickly lost sight of the suspect. Again, there were footprints. The police followed them to a ten foot concrete wall – where they ended. In 2008, a young couple was fishing off of a pier at nearby Ludden Lake. They heard noises coming from beneath the pier, directly under their feet. Something was climbing up out of the water. Thinking it was an animal, they shined a flashlight between the boards of the pier to get a better look. Staring back at them was a stark white face of a man. The couple fled towards their car. The creature followed. It was fast. As they drove away they could see a tall darkly dressed, caped figure running towards them. Two patrol units went to the pier. They found the couple’s hastily abandoned fishing gear and nothing else.

Phantom Stranger (October 1, 1999, Manhattan, New York)

A sinister entity was seen in the subways of Manhattan, New York on October 1, 1999. The witness was ascending the escalator at Penn Station and had reached street level when she noticed standing about 20 feet away, what seemed to be a male figure about 6 feet, 7 inches tall. He stood near the mouth of the entranceway to the station. His face was light gray (almost white), with thick brows and menacing eyes. He stood in a peculiar way, standing with his back arched, shoulders broad, his elbows pointing towards his back, and his head was tilted back as if he was looking at the tops of the passersby’s heads - it was like he was trying to choose one of them. The witness caught a glimpse of his face but she turned away immediately, and walked away down the sidewalk without turning back, feeling that if she would turn around for another look something would happen to her. For an unknown reason she felt tremendous fear.
Quick note from the editor here - This story seems to be a stretch at best, and barely paranormal at worst. This person could have easily been a mentally ill individual or simply someone with a strange posture. Also, the fact that the witness provides no personal information makes the story extremely difficult to pinpoint, especially seeing as this tale is only mentioned in the source below - which is a wiki, so take it with a grain of salt. Or iron. Both are helpful when taking down demons.

Henderson Island Monster (Henderson Island, Puget Sound, July 1893)

The first description of this bizarre event was found in the Tacoma Daily Ledger of July 3^rd, 1893. A group of men were on a fishing expedition at Henderson Island off Puget Sound when they (as well as a small group of surveyors) witnessed the creature in question. A loud noise was followed by a strong electric current and bright lights – and two men who touched the water were rendered senseless immediately. The creature that seemed to be the origin of the light and sound dived beneath the water at this point, but the light that shone from its body remained visible. The beast was described as 150ft (or 45.7m) long and was 30ft (or 9m) wide at its thickest point. Its head was supposedly larger than that of a walrus but resembled this in shape. It had six eyes, all of which were large and dull. The electricity that had previously knocked out two witnesses appeared to come from ‘copper bands’ encircling its body, and it flung out electrified water from hornlike protuberances on its head. In place of a tale, it seemed to have a propeller which revolved. Loren Coleman, a famous cryptozoologist, suggested that the Henderson Island Monster was an unidentified submersible object rather than a living organism. The witnesses would beg to differ. However, if it was a machine, where would such an awesome contraption have come from in the 19^th century?

Flying Humanoid (Detroit, August 19th, 2002)

The witness was driving their work truck through a storm - lightning was flashing, but there was no thunder and rain had not started. The witness happened to look upwards and saw what they took to be the Fisher Building - which is approximately 50 floors high and has a large glowing red ball on top. There were what looked to be birds, but they were apparently too large to be birds. They covered the ball and it appeared as if they were startled from the lightning in the storm, because they all flew upwards in a boomerang formation. There was a yellow glow as they drifted Southeast (heading towards Canada) which eventually turned reddish as the creatures moved. When the lightning hit the top of the building, the building lit up bright white. That was the moment in which the witness decided that they were seeing angels taking off. They said that they were not drinking, do not use drugs and had a restful night’s sleep before.
