Hi Arduous, I'm just now coming off Paxil ( an antidepressant) because it gave me crazy apocalyptic nightmares every night. It's a terrible thing to go thru. My friend has has apocalyptic nightmares about war and genocide since she was young as well ( with no psych. Meds to blame). I know PTSD sufferers, like my friend, have the nightmares as a subconscious way to "deal" with the trauma. In my case, it was obviously a result of my medication. R u on any meds? Do u have a doc to therapist? U shouldn't have to keep living with the nightmares...human beings CANNOT survive without sleep. It's a fact. Definitely talk to your doctor about it...and avoid eating sugar, especially chocolate, within 3 hours of going to bed. good luck!
