Last sleep study rem latency 125 min percent tst: rem 28.7. sws 16.9. effiency: 67.9. index: arousal 21.4, awakening 4.2. indicative of anything?

More data would help: The most important finding is that you are only sleeping 67.9% of the time that you are in bed. The arousal number cannot be interpreted without knowing the context of the arousals. You did not have many awakenings, but you must have been awake a considerable while each time. Rem latency is slightly long, but not enough to draw any conclusions from. Basically your sleep quantity is poor.
