Shadow Goblins

I've always been fascinated with the paranormal and I've been looking at this site for a while. I just thought I would post a story that happened to me when I was in middle school. Maybe someone can shed some light on what it may have been. I do have an overactive imagination, but I always try and find a reasonable explanation for odd and creepy experiences first. This one I'm just stumped on. (Sorry I don't have a huge amount of detail because it was about 10 years ago).

Around 10:00pm I was lying in bed in my room because it was a school night. Sometimes I'd just lay there and stare at the ceiling or look at things in my room for a while before drifting off to sleep. It's hard to explain, but to me in the dark, things kind of look pixelated like on a computer screen. Out of the dark I started to see little shadows. They were each about a foot tall maybe. No real features just outlines of shadows. I know it sounds silly but they were in the shape of little cartoonish goblins. (Can't remember exactly why, but they reminded me of something in the Disney cartoon Fantasia) They started out of nowhere and moved up from the foot of my bed to my face and then disappeared behind me. I laid there for a few minutes in awe and half thinking my eyes were playing tricks on me. After a few minutes it started to scare me. I ran out into the hall, turned on the light, and yelled for my mom. The shadows disappeared when I hit the light. I told her what had happened and she told me to quit being silly and go back to bed.

Sometime later I saw them again. I did the same thing, ran into the hall and they disappeared in the light. I again told my mother and got the same reply. I remember it happened at least one more time but the last time it was different. When I ran into the hall and turned on the light they were still there. I still saw them as shadows and they still came towards me and disappeared behind me. I yelled for my mother and she still told me I was being silly and that my eyes were playing tricks on me, even though I told her that I was still seeing them right that minute in the light. She sent me back to bed still seeing them. I eventually drifted off to sleep because I had no other choice. I never saw them again after that.

I'd just like to know if anyone has heard of anything like this. Was it my eyes or my imagination, or something else? I've had other "experiences," but as I've always been interested in paranormal things, I've always kind of had a good knack of scaring myself over nothing. Although I should also note that at the time I was into witchcraft with some friends. (Nothing negative though) I don't know if it has anything at all to do with this or not. Although other things that happened at that time, I credit them to being young and in a group of girls and scaring the crap out of each other. The "Shadow goblins" I just don't understand. If you have any questions feel free to comment. Thanks for reading
