You know when you’re an insane person and you get feeling really anxious so you become super conscious of the speed of your heart rate and then you subsequently start thinking about the speed of your breathing, but once you start focusing on your own breathing, it ceases to be involuntary, and then you suddenly need to actually consciously think about and manually manage each breath? Yeah, me neither.
I used to have this feeling when I slept in any bed that wasn’t my own. Any rhythms happening kept me up and it was awful. I figured out I needed specific textures to feel to stop paying attention and fall asleep. Mostly flannels and flannelettes.
