REM is of course dreaming. Dreaming is nothing more than clutter being cleaned from the brain. Images, background noise, conversations, old high school buddies, and so on. The brain de-clutters on average every 90 to 120 minutes during the night. When someone’s sleep is interrupted due to something such as apnea the brain gets behind in house cleaning. Once the sleep issue is corrected the brain has to play catch up and toss out all the not needed information. The forebrain is logical and wants to make sense of all this activity and puts the images in an order you can understand. Say you have the images being purged cat, cup, breakfast meal. Your brain knows cups hold water and that cats swim so you may dream there is a cat swimming in your morning coffee. Weird images, true but logical to your brain. …basically REM rebound is catch up housecleaning for your brain.
REM rebound is an extended period of REM caused by pap therapy. Generally an apnaec person will be the deep restorative sleep of REM and stage 3 sleep. Typically we have more events in REM which knocks us back into a lighter sleep. This also denies us REM. A person with severe apnea will go weeks if not months without REM. This is what makes you feel so tired. REM rebound is what happens when your PAP therapy allows you to reach a true REM again. I am at work now, but when I get home I will post some more info about it. Search "REM rebound" and "NREM vs REM sleep" in the sleepguide search engine.
Sleep Apnea interrupts dreams so when you fall back you begin to dream. If all is going well with your sleep...well chances are you will not remember your dreams nor should you try. If you write your dreams down in a book all that purged junk is refiled to be reshuffled and purged again... you know the same dream 3 nights in a row...sorry it isn't dream haunting its just tossing out the same trash night after night. relax toss out the trash and move on to some fun stuff!!
Rock do you work in the Biz?
fascinating thread. When my wife was not treating her apnea, she had very vivid dreams that she could remember. Now that she's on CPAP, she hardly ever remembers her dreams. Myself, I rarely dreamt/remembered my dreams before CPAP, then experienced a period of vivid dreams upon starting CPAP, and now am back to not remembering my dreams.
