Truecel trait: Your body refuses to REM sleep

Everytime I enter REM state during sleep I experience nightmares and immediately wake up. So despite sleeping 8 hours with excellent deep sleep which allows me to recover physically, mentally I feel like worse waking up than going to sleep.

Only cope thus far has been dude weeding it up before going to sleep cause I usually don't dream when I do that. Any other suggestions how I keep myself from bullying me in my head every night?
