The REM latency can be very useful though. Normal REM latency should be between 90 and 120 minutes. The first REM period usually only lasts 5-10 minutes.
There is evidence that a REM latency of 60 minutes or less is an indicator of depression. An REM onset close to Sleep Onset is sometimes an indicator of Narcolepsy, thought only and MSLT can diagnose that.

I don't know how to quote from posts, but from what you said what if you are above the normal for REM latency? My sleep study says I had 387 all night, 0 pre treatment and 220 post treatment (don't know where the extra 167 came from) If a low latency indicates depression, what does a high one mean? I do know that I was told that the sleep study would end about 5:30, but if I was in REM that they would let me wake up when it was finished... so I didn't wake up until around 6:05 (I felt so bad for the tech). Normally I do notice that the alarm clock seems to always wake me up in the middle of dreams and I feel very sleepy and it's hard to wake up. I hate mornings!!!

During sleep studies that is called the first night effect. For reasons unknown to me, the first REM period in a sleep lab is often missed. Stress to a new sleeping environment? Maybe why our sleep in a hotel room isn't as good as at home? I don't know, but a longer than normal latency for REM isn't any call for alarm.

What do the numbers represent? Maybe this isn't as simple as really awful math!

In the morning is when our REM periods last the longest and when we're most likely to wake. It's probably hard to wake because you're being awoken unnaturally and need more sleep. Can you dedicate more time to sleep? Even 20-30 minutes?

I love mornings.....but hate alarm clocks!
