My GOD! I just posted and my computer glitched and it didn't work!
To simplify. It's a hoax.
Voices: Someone else could have done it, easily.
Figures: Just someone walking around who we aren't introduced to, simply.
Door: I watched the door open and saw nothing special about it, no face, no orbs and we can't see the bottom of the door so it easily could have been opened from there.
Face in Door: as a Media student, I've done a lot of work with Final Cut Pro and Adobe Premiere and I know how easy (basic?) it is to overlay an image like that into some footage. I direct you to 'stargirl''s fmp of her friend playing a computer game while ghostly versions of herself loom over her, it's the same principle, really, just with a few obvious variations, FCP being a bit different from Photoshop. *shrug*
