I've only had a few experiences with creepypasta. One time when I was with a bunch of my friends to watch a WWE paperview 2 of them showed us the famous Ben Drowned story. It actually shocked the hell out of us and for a while I thought it was legit. It only took me a few days however to realize it was completely fabricated and somebody is just really good at hacking N64 games. But **** I gotta admit it still fooled the hell out of me. In fact most of my friends may still believe its real. Normally I don't really believe in the supernatural unless there's some kind of proof and whoever managed to pull this off must have had a lot of time on their hands.
I did learn more about other creepypastas but honestly they all seemed flat out ridiculous to take seriously. The Majora's Mask may very well be the best one imo. Still I'm not the type to go on websites just so I can intentionally scare myself so really not my thing.
