18. FYI: The leading nightmare treatment kind of involves lucid dreaming.
There are some medications that treat nightmares by reducing REM sleep, Breus says, but nothing has been as effective as Image Rehearsal Therapy (IRT), a non-pharmacological treatment developed by Krakow in the 1990s for sexual assault survivors. IRT requires the patient to write down their nightmares in excruciating detail, then change the storyline to include positive images and practice reading and rehearsing the new dream each day for several weeks. This way they have a cognitive-behavioral tool to deal with unpleasant images before they emerge in a nightmare. "It's not a cure-all, but 80 to 90% of patients report that IRT greatly reduced the intensity of nightmares and that it has a sustained effect," says Krakow.
Some variations of IRT even incorporate Lucid Dreaming Therapy to help the dreamer change a nightmare as it's happening. So basically Inception is real.
