Oh you better believe it. Since stopping Effexor and Xanax I have had dreams that go on and on. I will wake, be thankful the dream is just a dream, go back to sleep and take the dream up where I left off. Unfortunately the dreams are rarely something good. Most are filled with frustration and danger. I have rarely ever had sexual dreams in my whole life but I've had those too and they are bizarre. You could make a Pulp Fiction movie out of my dreams.
