Earlier, I used to have dreams. Sometime during my depression I stopped having them. I started going to therapy and few months later I started having dreams again.
So if medication can affect the ability (?) to have dreams, can it also affect nature or tone of dreams?
Hell, even the anti-nicotine drug (Chantix) gave me wild dreams. It was like having a nightmare but not being scared, like I was watching a horror movie. Looked forward to going to sleep. Free movie!
