I have been on several medications over the past months for anxiety. Right now i'm on Buspar. I am waiting for it to work but in the mean time, I have had some wild dreams. Some scary... If i do wake up from them I fall back to sleep after a little bit. I'm a pretty sound sleeper. It just felt like it has been years since I could remember a dream. Now I'm remembering them every night. I have never been on anxiety meds before so this is probably common, just a bit scary at first.
