Creepypasta.com is a freaky site with a great concept! If you love urban legends and freaky tales, this is your place! If you love the concept of adding on a paragraph to a started story, along with others to make a combined piece of work--you found your nirvana.
These "cut-and-paste" ("pasta") short stories and creepy supposed real life situations are placed there for people to get properly creeped out.
Stories like "Slenderman" and "The Rake" have a very creepy urban legend type feel. If you ever find yourself waiting around and playing on your phone, consider having this one bookmarked to keep you unsettled and happily distracted.
