A member asked:

When in sleep cycle does 92 yo have rem and deep sleep? in bed from 2100 till 1000 but fitful sleep. not refreshed in am even when sleeps thru night.

Polysomnogram!: If you want a precise answer to the question you will need a polysomnogram (psg) also known as a sleep study. If you dream, you undoubtedly have some rem sleep. But it may be adequate. Heartburn? Gastric reflux? Restless legs? Sleep apnea? Nightmares? Medication effects? Night-time urination? Spine or joint pain? All these possibilities can and do contribute to fitful sleep.
