The JREF has a very active YouTube channel through which we receive direct messages from both skeptics and believers. Sometimes we receive videos from YouTubers as proofs of paranormal activity.

Here we have one such paranormal "proof," in which the videomaker presents his evidence for the existence of ghosts. Before we respond, I thought we should ask our Swift audience to have a look at the video and provide explanations of exactly what is going on here.

So please view the video and post your explanations in the comments below. To inspire a little competition, whoever gives the most thorough explanation will win an autographed DVD of James Randi's famed escape over Niagara Falls.

Randi will judge, so please be thorough.
