In the General Section, there is a category called "Sleep and Dream Interpretation." Perhaps someone who regularly posts in that thread could assist with the interpretation of your nightmare-like dreams.
As a C-PTSD sufferer, I often have nightmares. I'm not really good at interpretating them though. They seem to be a symptom of the illness (as well as depression as they are depressing in thought). I don't really find significance other than that in them. I do, however, have difficulty in the effect they have on my mood / state of mind. The loss of sleep that they cause is also a problem.
