Is it normal to go without sleep for weeks on end with sublucid dreams

I have an unusual sleep pattern, I can go up to two weeks without needing or being able to sleep. When I do sleep, I have dreams that are sub-lucid, meaning, I have some control of my actions in the dream, but fail to properly complete any particular action. An example would be, if something is after me, I can try to run, but then my legs get ripped of, or I can try to fight back, but then I get a scythe to the head. All my dreams are nightmares, which all end with me dying, and I experience real pain when I wake up. This pain corresponds to the location of my body where I was wounded in the dream. I have no idea what is wrong with me.
