jeff the killer
i used to just be creeped out by him, but then somebody sent me a imgur link, i clicked it, and it was loving jeff the killer screaming and flashing inverted/whatever colors, where i had a heart attack and never clicked a image before asking "What is it..?" sometimes i just don't click links at all and ignore them.
opening my eyes in water
When I was about 5 or 7, i tried swimming in my aunt's pool with my eyes open, and then they started hurting like hell, and i thought (being the kid i was) that the water was washing away the color from my eyes and i would be color-blind, so even today i hate opening my eyes under water, or even in the shower for some reason.
Screamers. loving screamers.
These things make me want to loving throw my computer at the wall, watching a video then suddenly you're on the floor, however most screamers are very predicted and usually you can see comments/posts that go something like "godum screemers"
