Same nightmare over and over.?

I have had this nightmare about 20 times so far since January, but I been experiencing this for 2 years. the dream always starts where I go to sleep that night as in, in my dream I wake up where I went to sleep and it feels as though it's not a dream. My view of my dreams are always as though my eyes are half closed and blurry and out of no where I feel pain and this horrible looking black figure is always hurting me and I feel it. I end up paralyzed and can't move in the end and then I realize it's a dream and I shake my head and wake up. It's the most scariest thing eps when if I go back to sleep I go back to the dream. Any advice how to stop this or what this is? No stupid comments or remarks I'll just report you. Thanks.
