WHEN I WAS TESTED MANY YEARS AGO AND BEFORE MEDS I WENT IN AND OUT OREM 600 TIMES A NIGHT AND WOKE UP EVERY 20 MIN. TO THE MINUTE . . . I WAS DIAGNOSED WITH SEVERE NARCOLEPSY LOOKING FOR A MORE EFFECTIVE SLEEP AID. I NOW TAKE 1MG OF CLONAZEPAM
Total sleep time was about four and a half hours, with "77 arrousals 4 awakenings". It's possible you just never got around to REM sleep, as that sometimes doesn't happen for several hours. Most dreaming happens towards the end of our sleep period, and with a high level of sleep deprivation, what little sleep you get could be deeper levels, as indicated by the time you spent in N2 and N3 sleep. You need to find an expert who can interpret your results. Sadly, some (most?) sleep "experts" are not sleep experts, they are sleep apnea experts who can do little more than diagnose sleep apnea and prescribe cpap machines. That was the results of my sleep study. "No sleep apnea, but you keep waking up so here have a cpap machine and have a happy life". But doctor, why do I keep waking up all night long? "I don't know, just use the cpap machine and have a happy life".
Find a doctor that knows how to interpret these results and tell you why, or at least tell you where to go to find out.
On a side note, the clinic I went to went out of business not too long afterwards...
You need to discuss with your doctor. That is the best person to both interpret the results and give you the best advice.
