Someone mentioned it might explain a lot of the 'shadow person' footage people post here, like the ones from abandoned hospitals. They said the brain under stress can make you see or feel a presence that isn't there. It made me look at those videos differently. I watched that famous 'Mel's Hole' clip again, where the guy films something moving in the dark pit. Could that just be his mind filling in blanks? What's a video you've seen that could be explained by a trick of the mind instead of something paranormal?
