I used to dream a lot; in the past year since I started taking THC as medication I haven't had any. I put this down to the THC basically letting you dream while you're awake, which seems to be more effective than doing it while asleep. As far as I can tell the purpose of dreams seems to be a way for the brain to visualize its own structure and repair itself (i.e. retraining your pattern matching on other inputs, not just visual).
