I try hard to focus on feeling tired. I let go of control of my body and mind, making my brain relax and go limp. I try to keep my mind clear of thoughts and concentrate on how tired I am. I also pretend to feel sleepy because it’s like my brain is tense when I go to bed. I need to slowly shut it down, similar to turning off a computer, but it takes more time and effort because the brain has been active all day. Unlike a machine, the brain is a living organ, so it’s more of a manual shutdown process.
