I have wondered is it the angel of death? The spirit of a person who is going to die returning to warn them since time does not exsist outside this realm? Something evil that marks a person or people for death? I am open.
This idea came from the fact that the Mothman was seen for exactly 13 months prior to the collapse of the Silver Bridge, then just disappearedThe belief that Mothman was some kind of death omen developed after the sightings were over, although I don't know who first proposed the idea The movie doesn't follow the actual events very wellIt is very loosely based on the book The Mothman Prophecies by John KeelI have read the book but I don't remember if Keel suggested the idea of the death omen connection Loren Coleman has also written about the MothmanEDIT - Oh, you mean you would like our opinions on itHonestly, I have no idea what it might have beenSome have suggested that it was a sandhill crane, but that doesn't match the descriptions closely enough.
If you're willing to spend $9 dollars on Clearasil PadsI use them when I start to break out and by the next day my zits get small or go awayI really like it and it never failed on me :) I'll give you the link on how they lookThey sell them at walgreens.
