“I once had a favourite image for falling asleep…After waiting a minute or two before switching off my lamp, collecting awareness so that I would fully appreciate the embrace of darkness, I turned face downwards, sprawled my arms and legs, and my bed became a raft which floated me out onto the sea of night. It produced a sensation of luxury; the more seductive for being enlivened by an almost imperceptible thread of risk.”
--Somewhere Towards the End: a Memoir, Diana Athill
I love this image.
To go to sleep, I often imagine that my alarm is about to go off. Thinking that I must get out of bed helps me feel tired.
