"We were walking in the dark, and I heard the heavy breathing of an animal very clearly because it was running. I turned my flashlight to a quiet place. It must be this place, but I couldn't see anything. I don't know if this kind of thing can make itself invisible when a foreign object approaches? "
To be sure, at least some reports about hairy bipeds are practical jokes. They are either lies, or some people are really teased by pranksters in costumes. Some hairy bipeds (such as "animals" seen by many residents in Lowton, Oklahoma in February, 197 1) proved to be "people" with dirty bodies, beards and mental illness, just as many reports about 19 th century "savages" did. In other events, the hairy biped may be a bear. However, we can't generalize, and these explanations can't cover all witnesses, especially some witnesses now.
