What did you do about it?
I have the opposite issue most here report, I have a lot of deep sleep and very little REM. I have been trying to increase it. I track with a Garmin Fenix 6 and have noted a high timeline correlation with when it says I have REM and when I have dreams…wake from a dream, look at watch time, the sleep report shows a small block of REM at that time. I know its not perfect but seems to be pretty good.
