My understanding is that PTSD quite commonly includes nightmares, which must be very unpleasant even if it has no further consequences. I see that, in your paper, you briefly consider PTSD nightmares, distinguishing them from normal dreams in that in the latter the dreamer's behavior seems odd, while in the former case, it is the environment that seems odd. For what it is worth, in my dreams (non-PTSD not-nightmare), the environment usually seems odd and I am just trying to cope with it as best I can.
