Nightmares effecting me almost everyday

[pyrosan]

So, I've been having nightmares ever since i was a kid. they were off and on when i went to high school and then continued to get worse when i went to college. My dreams are mainly about people trying to kill me... I'm always the main target or anything that has to do with death. Sometimes I can't even sleep because I'm scared of having them again. When i was younger i would see the walls melting, i was terrified and she told me it was a nightmare and to go back to sleep so i did. Another time i told my mom that there was oil on the floor which I don't remember. I've also been told i used to sleep walk when i was a kid. I just want to know why do i keep having these kind of dreams practically everyday?  Has anyone experienced some of the things I've said?
