Pretty interesting - I've read that extra terrestrials often try projecting a more pleasing appearance onto themselves when invading people's private space. However, this technique is not perfect and takes lots of concentration so the victims sense that something's off about the "vision" they're experiencing.
Pretty sure thought that 99.99% of the footage is a scam beyond scam. There's one vid which I'll have search for again where they're filming magicians and it's high def - the only one that made me somehow faintly accept that such a thing might be real.
