Hey, I'm only 13 and lately I've been seeing small black things that turned up to be chasing me, I have made sure they're not my hair on my eyes or something like that, or maybe some illusion out of my mind, I have SEEN them, crawling on the wall or on the couch or somewhere or just flying in front of me like poof, they are real, is it possible that I'm bieng haunted or something? Or there is a specific explanation about this?
