I think that Edgar Allan Poe is not crazy, but he does seem to be a bit strange. He writes about how some paranoid person is scared of an old man's eye because it reminds the guy of a vultures eye. So you know what the guy does? He kills the old man just because the eye was scary. Then when a neighbor hears the old man screaming, they call the cops. The guy then dismembers the old man and puts the body parts under the wooden planks on the floor. When the cops get to the house, everything is all good. But the guy can't take the guilt any more, so he screams "villains" and rips the plank off the floor and shows them the body parts. Now Poe was most likely not a crazy man, but he seems to have some problems.
