I spent the night at a sleep disorders clinic for testing for possible sleep apnea or narcolepsy.?

I slept for seven hours at a sleep disorder clinic. The technician told me that I did not have sleep apnea. He did say, though, that I have NO REM CYCLES. How would having no REM sleep affect me? I have sleep attacks during which I am unable to control my need to lie down and sleep. My doctor wanted me tested for sleep apnea or narcolepsy. I cannot see my doctor until the end of May so I would appreciate it if someone could tell me what no REM cycles does to a person. Thank you.
