Interesting video. Don't know what to think about it, but yeah, I suppose if it's fake, it's a nice attempt.

I was just talking to a friend about this one time we went to his house at night to play video-games. He was drinking vodka, but I was sober...
Anyway, I thought I saw something by the corner of my eye, so I turned around and saw a white thing going out the bathroom and down the stairs. It gave me a very deep feeling of melancholy. I was impressed, though, so I kinda stared... my friend noticed and told me "so you saw her, right?"
Turns out the white figure I saw was some sort of female apparition that sometimes shows itself and other mutual friends confirmed it.
I convinced my friend to find out what was the house's history, but we had no luck... no one would tell us anything.
