I might be wrong about this but I don't think (based on what I read) that micro-awakenings only happen following the ending of REM. As far as I know they also might happen during REM, or even (rarely) in between two NREM stages... Most sleep stages charts are very generalized, in actuality it's not that clear cut... So it's better not to assume that an awakening means NREM for a few minutes. |
