Pooka (1990, Ashby-De-La-Zouch, Leicestershire)

A resident of the aforementioned village awoke in the middle of the night and witnessed what she believed to be a being known as a Pooka in Irish folklore, sleeping over the pelmet of a window on her landing. The creaeture looked similar to a small piglet, but had a long, pointy nose and no visible tail. Pookas are shapeshifting tricksters and mischief-makers in Irish faery lore, but as far as I know they have never been described as piglet-like entities.

Ufonaut (1990, Near Kiev, Ukraine)

A local woman was gathering mushrooms in a field when she was approached by a strange figure more than 2 meters in height. The figure was dressed in a shiny dark diving suit and a helmet. The stranger shone a beam of yellow light at the woman and disappeared, having literally evaporated into thin air. The witness reported a strange aftereffect; according to doctors she completely ceased to attend to the toilet, even after eating and drinking regularly. Apparently the doctors removed the waste manually. Suddenly in 1993 the normal functions of the witness were unexpectedly restored. This account should be traced back through its source and the hospital that analysed the witness should be found. If this can be done, then the story can be either debunked or validated.
