A little bit off topic, but I watched this podcast today about sleep https://www.youtube.com/watch?v=BMTt8gSl13s but it also covered a theory about PTSD, that in REM sleep while memories are being consolidated, adrenaline is usually turned off, but in folks with PTSD, the adrenaline stays on, and this stops the traumatic memory being integrated. They suggest that trying to make the mind calm just before going to sleep might be helpful.
