How do I forget what I saw?

[Jake]

Today I was on the internet just lookin up stuff and I stumbled over something called best gore. I clicked on it and I was cerious so I clicked on one of the videos that said car crash caught on camera. My first instinct was that it was fake until I looked around a little more on the site and saw the catagores and I clicked on decapitation and saw a mexican cartel guy cut off a females head with a butterfly knife. That's when I thought it was real. I look around and other sites say that everything on that site has a 80% of being real. HOW DO I FORGET ABOUT THIS.
