Try writing them down as soon as you wake up.

I did that then brought them to T's and we talked about what they meant or represented for me.

Three o'clock in the morning I was scribbling down whatever I could remember and the feelings it brought up. (fear, anger sadness)

It helped.

PS I forgot to add, she had me change the endings, so they became nonthreatening.

There is a name for it, image rehearsal or something like that.
