If you’ve never heard of creepypasta, it is basically scary stories people post online. Most of these stories are told in first person and are meant to be read as though they are true accounts. You’ve surely come into contact with some of the lowest forms of creepypasta in the form of comments on YouTube or similar sites which typically end with “Repost or she will appear by your bed at midnight to cut your eyes out too!” or something similar. There are some great stories out there in the creepypasta genre though, and you can find them on YouTube, just not generally in the comments section.
You can find them on the channel of Mr. Creepy Pasta.
