Thread: Recurring nightmare - chased by a demon

As I stated above, this has been a recurring nightmare for me, happening every couple of months maybe. To give some background knowledge on the dream and anything I feel may be related:
My parents are divorced, and have been for 7 years. I am 15 years old, and I switch between my moms house and my dads house every week. I have a very good relationship with my dad - we get along great all the time. However, I get into a lot of arguments with my mom. She is very controlling and we often get into disputes regarding different aspects of my social life. Now, back to the dream.

The dream takes place in my moms house. I usually start of talking to my dad, even though I am at my moms house. I cant remember if my mom is there as well, but if she was it was only a small part. Soon afterwards, I leave to a different part of the house where I am alone. Suddenly, out of the shadows some sort of black, twisted looking, SCARY, demon emerges and approaches me. I see it, and yet I am frozen in fear. I seem to be in shock, and I can do nothing. I cant scream, I cant run, I cant protect myself. It slowly begins getting closer, and closer to me. Finally, when it is nearly upon me I manage to yell for help. My dad, and, for some reason, a police officer run to my rescue. The demon disappears though, and wasn’t seen by anyone else. The police officer is now assigned to be with me all the time, in case the demon returns. Everything is fine when I am with him, but eventually I get separated from him for a second. Again, alone in a certain part of my moms house, the demon emerges again and, as before, I am frozen in fear and I am in complete shock. At the last second, I scream before the demon touches me. The dream repeats itself: I am constantly with the police officer and my dad, and for whatever reason they leave for a second and sure enough the demon appears. It probably repeats about 4-6 times, before I wake up TERRIFIED. No one else ever sees the demon, except it always seems to be waiting for me.
Now for how I was feeling in the dream:
I am feeling scared out of my mind throughout this entire thing! I am dreading the next appearance of the demon, although what scares me the most in the dream is that I become paralysed in fear! I can’t think of any emotions that were in the dream apart from terror! Fear!

All in all I have had this dream about 4 times, and I hate it when I do experience it. It often leaves me feeling a little ‘jumpy’ and scared when I am alone for the next day or two, or whenever I begin thinking about it. For example, just writing this all out has made me somewhat scared. It hasn’t happened for about 3-5 months, but it is still as vivid in my mind as if it happened last night.
Does anyone have any ideas on what this dream could mean?
