I've had many very awful, horrific nightmares, for sure, @
VanillaGhostie - and I've been having these dreams long before I started taking medication, too, so, for me it's not necessarily med's related.
Yes, complete strangers dying very violent deaths. One time I dreamed I was in a monstrous concentration camp, I'll never forget that one. I won't go into the details but was so glad when I woke up from it. The mind can create a fantastic array of imagery.
I personally believe my nightmares are being influenced by anxiety, depression, and the whole sense of hopelessness that may come along with it. I mainly have them when I get particularly low, usually triggered by an external disturbance.
