Shadow, Make Believe, Or A Demon?

Let me start off with saying I don't believe every single time you see something it's automatically a demon. This is the one time I may disregard that statement. I've seen this, thing, many times, gladly it has stopped appearing.

The very first time I ever seen it was when I was five. We had just built an upstairs. More of a frame then anything. My mother and I where folding clothes and taking out clothes to hang. For some reason I can't remember my mom went outside to hang clothes and I stayed behind. I started to go out but before I could even go outside the door frame I look at the room next to mine. Underneath the bed was a pair of red eyes.

I hid behind the way, occasionally peaking out to look. I had thought about running out as fast as I could. I had a horrible feeling it would grab me. I ended up screaming and bawling for my mother to get me. A little detail about the room, it was my second brothers and my fathers bedroom. Like the rest of the house it was pure concrete. It had no windows, because it was in a hill.

The first time I seen it with a group of cousins, we were at least 8 or 9 at the time. We joked around telling ghost stories and such. Making up our own versions of "Bloody Mary". At some point my first cousin brought up a story. That these old deer horns would light up with "red eyes" on each point.

I went along trying to scare my city cousins. We told them to say "red antlers" 10 times in a row. They did and we all went back to the room were they hung. Instead of us screaming trying to scare them. It actually worked. The "eyes" turned to us. We all freaked out, pushing and shoving each other out of the way and left the basement alone from the rest of the week.

The second time it was seen was with my friend. We were about 12 at the time. We went down into the basement to get ice-cream. Before I had even gotten to the third last step, my friend screamed and pushed past me. Being afraidy-cat I ran right after her. She ran outside crying. I kept asking what happened. Finally at some point she told me a black shadow with red eyes floated from one side of the house to the other. Needles to say we didn't get ice-cream for the rest of the day.

The last time I seen it at my old house was with another friend. We were 13 or 14. Being extremely childish we went outside in long flowing dresses pretending to be vampires. At some point I looked into the sky. The moon was out but it wasn't the brightest. I saw what seamed to be the outline of a person crouching on the highest point of the roof, just watching us. I quietly asked if she had seen what I was. As a dumb response she answered "The person on the roof?"

We both ended up screaming and running inside. I told her about a white ribbon I had found lying directly outside my door the day before. In some weird twist we decided that was the reason why we seen it. Then we promptly smeared our blood on it and cut in half. Why did we use our blood? We where scared and some how this seemed as a good idea.

I have moved to live with my mom. I told her about it and all she has said is "It's your fathers karma manifesting." or something close to that. Yet I have seen it here... Though it doesn't scare me like it use to. Also it doesn't have red eyes either.

I have a few more stories that happened relatively soon I'll post them later. What do you think it is or could be?
