This is my case, my trick is to imagine pleasurable fantasy scenarios and go over the smallest details.

I go a little bit more meta, and start imagining myself sleeping.

Kind of… say I’m part of the Start Trek crew. I imagine how would it be to sleep in the Enterprise. How is the room? What furniture is there? Is there a window/screen showing the outside? Etc…

For me, works wonderfully.

Sounds similar to my trick, although I'm not sure if I really delve into details. I think the main purpose is to push out everything else from my mind, since whenever I have insomnia, it's not because I'm looking at my phone, but because I can't get something out of my mind.
