Has anyone experienced the shadow people

Just curious to hear some stories if so, I tried posting a story i had but the group tried saying I put certain words in it that weren't allowed or whatever the fuck the words weren't even in it but anyway yeah yall ever seen shadow people

My story was a mate of mine would freak out whenever we were on the gear, saying there's people in the grass outside and that they're insanely fast. Sometimes I'd call out to them and he'd fucking loose it, I experienced it for like a month or so and the first couple times was freaky but understanding it was just my brain playing with me I stopped paying attention to em, haven't experienced it since
