When I was 7 or 8 in the middle of the night a shopping centre I live right next to had a fire alarm go off and I even remember during a dream I was having I could hear the alarm during it. Anyways my entire family wakes up go to my room looking through the window to see if everything is ok, after I think half an hour the alarm stops we all go back to bed. As I am laying in bed I felt very uneasy all of a sudden open my eyes look up and above me I see a shadowed figure hovering above me. It looked like it had a trench coat and hat, almost like a silouhette of the wrestler, The Undertaker when he wears his trench coat and hat. The thing was just pitch black with the exception of red glowing eyes and its hands looked like claws. Obviously I shat myself, put my blanket over my head and after five minutes managed to gain some courage and slowly pulled my blanket down and it was gone. Turns out what I saw was a pretty common phenomena just google "shadow people" im sure you will recognise which one I was talking about when you see the two common examples...
Oh and half a year later from that incident me and 2 mates of mine are in my parents room rumbling and my parents have a bathroom in their room. The door was a sliding door which was slightly opened and I saw a pitch black claw like hand gripping around the door tapping along it. The kind of thing you expect to see in a horror movie when the monster is watching its victim through a closed door. I asked my mates if they saw it, but they didn't see it.
I know it sounds like I might of just saw things that might of been a fragment of my imagination but I can honestly say what I saw was clearly vivid and I remember it clearly like it was only just yesterday, to this day I almost never look directly up when I sleep.
