Trazodone Hydrochloride and nightmares

The doctor gave me Trazodone to sleep at night. I was going through a bad time taking care of my dieing husband, working full time and taking care of the kids.
It gave me severe nightmares, ones that were so real that it was like they were in 3-D. Its hard to explain. I started to hate going to bed at night.
Then I got smart and quit taking the stuff.

I take 150 mg at night, but taking along, it makes me have terrible immobile nightmares. I take 2 mg of Ativan along with it at night to mellow the trazadone out. Both of them together makes me sleep like a log, by itself, I just can't take.
