I know exactly what you mean.
It’s like sleep is trying to pull you in with whisps of itself like the enticing fingers of a lover. You act coy, trying to keep afloat because the boundary feels… Exquisite. The whisps become more demanding little by little until finally you succumb and let them take you in and it feels like floating though clouds of immaterial boobs.
And then you are asleep.
Thanks, really interesting!
