Tangentially related: recently I've taken to doing a kind of "meditation-like" thing while trying to sleep where I imagine the number 300 visually, and attempt to count down towards zero, decrementing this counter visualization in my mind's eye. For an extra challenge, I try to do this while mentally saying the word "tock", but NOT mentally saying the current number. I find it extremely difficult, which is stimulating enough to keep my mind from wandering to places that tend to keep me awake, but not so stimulating that it prevents me from sleeping.
