Peeking at the TV without the glasses on is a classic gesture when I'm afraid to watch something too lol Though for a scene in "Bugs" I had to literally hide behind my hands so that I wouldn't see anything, not even blurred shapes or colours.

So yes, SPN is freaky and if you have low tolerance to begin with it could be REAL SCARY, that's for sure. I'd advise you to try again in daylight, some people on my flist watches it that way ;-)
