whilst watching paranormal activity with my mates I started to get all hot, tunnel vision and then i tried to stand up and fell down. I shouted for them to turn the light on and they were laughing thinking I was joking and then I just heard them say 'OH MY GOD' and apparantly I was really white with really large pupils..

I think it happened because there were loads of us sat together and my breathing was short due to being all hunched up....then at a tense moment I was shocked and I think I went into mild shock.....(as shock is just lack of blood to vital organs)

Scary stuff.
