At this point you could probably create creepypasta just by reposting the pre-Disney versions of European fairytales
Maybe the versions written down by the Brothers Grimm, or maybe the source material they were using - even the Grimm versions are somewhat sanitized
A lot of fairy tales kinda come down to "don't go into the forest you idiots"
Though there also is an element of "but if you do, bring back some of that witch gold"
