Yep, I'm having a lot of bad dreams at the moment. Mine are mostly being chased by murderers too, and I usually wake up with my heart racing. I wonder how often people without PTSD dream this type of dream? It would be interesting to know! I've had these dreams on and off as long as I can remember, and found out recently that I'd likely had PTSD from a young age. I guess I never thought about it much before, as I just assumed that my experiences were what everybody had! As a child, I had even thought that flashbacks (which mostly happen at night) were some kind of nightmare-hallucination thing, even though I was awake. I actually thought everyone must have them, horrifying as they were. I had no idea!
