These are my top five favorite creepypastas that I've seen. Hopefully, there isn't more than one creepypasta under these names.
1: A Game of Flashlight Tag
3: Bedtime (more specifically the first one)
4: Ronald Mcdonald House
5: If You Lost a Loved One
And some special mentions to:
Squidward's Suicide for being my favorite lost episode creepypasta (because it's one of those with a plot in the actual episode as well.)
Sibling Rivalry (Just such a realistic creepypasta, and so sad as well.)
And that is all.
