This is not a creepypasta, but rather something that really happened. It’s hearsay, I guess you could say, because I’ve never experienced it myself. Instead, this is something of a friend of mine, that they told me.
They used to tell me about this being called the Shadow Man. I still don’t fully understand what he looked like, other than a person made of shadow. They used to tell me that the Shadow Man followed them all the time, though never directly laid a hand on them. I always wondered what the Shadow Man wanted from them, then, if they never did anything. Eventually, this person saw the Shadow Man as sort of a twisted guardian. Like that he wasn’t evil, just strange. They told me they danced with him sometimes. They also told me about a fever dream they had. The details are fuzzy, it was explained to me a long time ago, but in essence, there was the Shadow Man, and some being of blinding light. I recall them telling me they had a sort of battle, but not a physical one. They’re not sure if it was a fever dream, or something that actually happened to them. Neither am I, really.
