I am struggling with depression and GAD after a blessed3 year remission. Suddenly I am having horrible nightmares not just once in a while, but several times in a night. I'm on Effexor XR, Risperdal, Ativan, and Ambien CR for sleep. Could these meds be causing the nightmares, or are these dreams just indications that I need more meds? The dreams are about real life events, horrific, and recurrent. What do you think?
