Thanks to Jenny for posting this question:
“We often wake-up in the morning out of or proximal to REM sleep, making dream recall easier – how is this affected by the frequent awakenings and sleeping only in bursts of less than 90 mins? Does this affect the cycle of 90 mins and also do you still have a last third of the night?”
