I'm so sorry you've been having traumatic dreams.

I can't say if the flashbacks are over, but the numb state you are in sounds like dissociation to me, too.
I'm in that state myself most of the time these days, but sometimes panic or strong trauma feelings will break through briefly before being shut down by the dissociation again.
I know it's a defense to help keep things functional, but then the dissociation itself can get really bad (in my case as in strange unreality feelings, disconnected from the body, can't move, etc), and then it's not so functional anymore.
One thing I have found to be helpful sometimes is watching these really wonderful naturescape videos by Louie Schwartzberg called "Moving Art". They are all on Netflix if you happen to have that, and other places too. Anyway it's just music with scenes of flying over various landscapes, watching flowers open and close and plants in time-lapse, night skies, etc and I find it to be very moving somehow. It makes me *feel* for awhile. They're my go-to comfort videos these days, especially if I'm really dissociating badly. Are there any videos, movies, music etc that typically can get into your emotions?
