I also have dreams of body parts quite frequently, however my trauma has nothing to do with body parts. It's weird though, during my dreams I am not at all disturbed by the blood and limbs . What disturb's me is when I wake I don't feel a thing. One might consider these horrific nightmares but I feel nothing. Is this common or am I a total psychopath!? :S
Psychopath? No, of course not. It is pretty common, one could say "normal" for those with PTSD to experience a kind of numbing. The degree of numbing can in itself be a bit of a shock. It can happen with all kinds of emotions, all kinds of events.
