various anti-depressant / atypical anti-psychotics can give you weird dreams:
Trazadone as mentioned above,
Mirtazipine is a very strange one [ some people report enhanced dreaming when mixed with marijuana; I never found this to be the case but can see how it would be possible, mirtazipine has some strange mechanisms of action not just sedation]
then there's Melatonin, not an antidepressant but a natural supplement to help reset your circadian rhythm. It can give you really vivid dreams. I haven't taken it in a long time but for 2 years I took it on and off, I would stop taking it when the dreams were getting bizarre (also when my insomnia was worst). The dreams weren't bizarre like supernatural, they would just be about everyday ordinary things. But then I'd wake up and not be able to remember if the conversation I had with a roommate was a dream or something that actually happened
