To sleep, perchance…

In the 2025 Hobonichi Weeks, on the page for the week of February 24th, the quotation is from the actor Rinko Kikuchi, and it's a tip for getting to sleep easily:

Relax, and put your thumb and index finger together. Concentrate all your senses on the surface that is touching. After a while, it will grow warm and you will feel as if the boundary between the two fingers is disappearing. Keep focusing on that vanished boundary, and you will fall asleep before you know it.

Does it work for you? I haven't had much luck with it, but it's not a bad idea!
