I hate sleeping because 90% of the time I will have a nightmare.

Nightmares I can handle.

But every one in a while when I get stabbed or shot or cut, I will feel intense physical pain and even after I wake up I will feel pain for many hours. The weird part is that I will sometimes have a real scar when I wake up from where I was shot, stabbed, etc in my dream. This happens about 2 times a month.

Is my skin bad or is there something really wrong with me? How can I solve this?
