How Do You Sleep QUESTIONS

Looking at all the Beatles and John Lennon songs, I’m reminded of the fact that Lennon mentioned the topic of sleep a few times. I’m Only Sleeping was on the Beatles’ Revolver album, though I first heard it on the US LP called Yesterday and Today. It starts off:
When I wake up early in the morning,
Lift my head, I’m still yawning
When I’m in the middle of a dream
Stay in bed, float up stream
Then, for the Beatles white album, Lennon writes:
I’m so tired, I haven’t slept a wink
I’m so tired, my mind is on the blink

The tone of the vicious Lennon attack on Paul McCartney, How Do You Sleep is contrasted with #9 Dream in my mind.
So long ago
Was it in a dream, was it just a dream?
I had know, yes I know
Seemed so very real, it seemed so real to me
1. How do YOU sleep at night?
2. Do you remember your dreams?
On those nights I sleep for six or seven hours straight, I tend not to remember my dreams. But on the nights I have a lot on my mind, I might sleep for four hours, then stay in bed, feeling that I had not slept at all the latter part of the time. But I know I have, because the dreams are so vivid, it’s as though they were real.
