Is it normal bright collars and edgy music makes me fall asleep ?

I dont know but I have this thing were I cant watch certein colars or I knock out i dont know but a lot of flashy lites and colors that are to bright or that look odd with the right mix of errie or edgey music makes me fall asleep and it doesnt matter what time of day it is It makes me fall asleep thats why its hard to watch " Witchblade " becuase it puts me to sleep with all the flashy lights and hard edgey music as well as that the movie fright night made me fall asleep within the first ten minute just becuase the intro music and the land scaping of the production I dont know . Is usually the type of music that sounds like a fast sharp quick violin strokes and electro type edgey music and alot of bright bright colors and colars like black and red together and the music on firght night put me to sleep just in the intro becuase the music and I hate it really . I auctully do not know what sets it off I do not understand why these colars effect me like this though but it knocks me out sometimes I oversleep becuase this is like a istant sleeping pill . Is this normal and its not becuase I am already sleepy becuase nothing else puts me to sleep except these mixed patterns colors and sharp sounds I have no idea how this puts my brain into a sleep but I cant stop it . I asked someone and they said do you have epilepsy ?" Im like I dont think so but I do get random spasms all the time but not siezures does this mean anything ? "On top of that I have bad isomnia Also it doesnt do anything with bright colors that are not movie but ones that flash and quick music .
