well it wasnt anywhere serious like that, but it's quite dark in the room im in and the screne flicked and blinked and maybe not dizzy, but it made my vison apear blurry((sorta like when you cross your eye's))
and thats what made me lose my balance. but then again it may affect more than just epilepsy sufferer's((i know i dont have it)) I do remember watching a program about these event's and tho its a strech, they said every person can be affected by a certain pattern. it was just very unlikley it would happen
