I think you maybe do have sleep apnea, i went for the overnight test years ago and they found out i had almost no REM sleep. I sleep with a machine now, a usually do pretty great with it, sleep at least 8 hours a night now, except when every once in awhile i'll sleep in the day instead of night. I think thats because my sleep is so good i don't want to wake up!! REM helps us dream and heals our bodies. Good luck
