For as long as I can remember I have been having dreams of death.

When I was 3 years old, I had dreams of killing people from movies and being killed by a blood thirsty dog, now its even worse. Now I am having dreams of not only death but a torturious death. I had a dreams like being tied to a chair then being tortured and killed, being brought back to life, and being killed again. Last night I had a dream that we were fighting in a war, I got caught, had evferybone broken in my body then had my head caught off.

Is that normal?
Sorry, I would have put more detail into it, but I had put detail then my computer shut down on me so I just put the basics.
