Lucid dreaming is being aware that you are dreaming while dreaming. Some therapists use techniques like lucid dreaming and dream incubation to help patients reduce nightmares or guide dreams. Lucid dreaming involves teaching patients to realize they are dreaming and then take control of the dream. Dream incubation involves having patients visualize a problem before bed and try to dream about it to potentially find a solution. Therapists have patients practice changing nightmares into less frightening dreams by rehearsing new dream scenarios.
