Bad dreams

Every night I been having bad dreams...BAD dreams, I guess nightmares. I won't go into detail. They are very detailed and very long. From one situation to the next from one part of the day to the next. And each dream is different for that night. Now here is the bad part...like the dream its self isn't bad enough, which trust me it is. When I finally wake up the dream continues. Even with my eyes open. Hence, the getting out of bed and doing something else. The last few nights I read for a few hours, the time before that I caught up on some recorded TV shows. Tonight I thought maybe if I talk about it it will go away. I try to pray it away while I'm still in bed, but once the prayer stops I fall right back into it right back where I left off. This is overwhelming consuming. I'm sure it has everything to do with my medicine from my surgery. I have cut back to 3 times a day now instead of every 4 hours. Which means no naps anymore. Maybe I should nap then I won't be sleeping so hard at night??? What ever is going on has got to stop. I command it to stop, in the name of JESUS! Even now when ever my mind stops what i am doing I go into the next page. Please help me...
