It seems strange to me that your therapist is putting so much emphasis on dreams & remembering your trauma.

Occasionally I will mention a dream to my therapist but it is generally just a way of getting the discussion going. If I go through a patch of nightmares then she has in the past gotten me to track them, write them down, but hasn't spent any time really analysing them.

There is a heap of stuff on the internet about repressed/recovered memories. I think I even made a post here (if you use the search function) about trying to remember.

Personally, after 18 months of therapy, I think I've accepted that I'm not going to remember all of my trauma from 5 - 7. That the snippets, feelings, music, images, sensations are probably all I'm going to get. Accepting that was a relief in itself. And now I'm attempting to concentrate on what I do have, not what I don't.

You have every right to ask your therapist questions about his methods, why he does what he does, expectations. You have a right to research different methods of therapy and you have the right to chose another therapist if this one isn't the right one for you.
