From youngest childhood, as long as I can remember, I had this thing that lived in my room. I was the only one who could see him (it was distinctly male - I knew just by the feeling he gave me) but others would feel his energy and it creeped them out, or in a few cases frightened them so badly they couldn't be in the room when he was.
He normally occupied a corner of whatever room he was in, up near the ceiling. He was rough looking, scaly, dirty, sparsely haired with an unnaturally wide face and his knees worked backward, holding him in the corner. His features were never super clear so I can't really describe his face much more than the shape of it.
While he could be felt as scary, creepy, or downright hateful by others, I always felt comforted by his presence, and when he was not there it seemed "off" to me. He would be there for weeks at a time, then be gone a few days, and return looking almost refreshed, if that makes any sense.
I felt protected by him, but others hated his presence to the point where my mom tried techniques like trapping him in a dark mirror, smudging, and banishing. (I don't understand those things for the record, as I never dabbled in any of it, I just remember her talking about what she was doing when she did it.) None of it ever worked, and he always returned.
We lived in motels, apartments, shelters, and no matter where I was he always found me, he watched me. Never said anything, never came down from his corner, never tried to communicate, save for once, when my brother came into my room in an apartment suddenly, and I saw his head swing quickly from me to my brother. He saw my brother, but my brother did not see him. (He stared at him until after I answered my brother, and he left the room, before resuming watching me- I say stared, because it wasn't the same kind of watching that he did with me, it was almost angry.) I could tell if he was feeling something although I'm not sure why, and though I tried many times to talk to him, he never showed he could even hear me.
He stopped showing up when I was around 20, and I haven't seen him since. I just wonder if anyone else ever saw something like him, or knew what he might have been? He was NOT human, but humanoid, and his joints worked the wrong ways. He had long arms and legs, and a rather short torso, so standing up I can imagine he would have looked rather odd, with his small torso, long limbs and wide face.
I have always been more sensitive to ghosts/seeing things others miss, perceptive to things outside this word. I have experienced other paranormal stuff, but those can be explained by deaths in the area, or the fact that I was in a graveyard at the time, and nothing else non-humanoid.
I call him creeper because of how he made others feel. I NEVER felt anything but safety and comfort from him.
