[inafewwords]

Seems to mirror my experience. I try to nap in 15 minute breaks at work. 30-1hr at lunch break (I eat while I'm working) so I have mid day personal time. Seems like the same skills of quieting the mind. I do a relaxation breath of (in = 4 count, hold = 7 count, exhale = 8 count) 3x

I never fall into a deep sleep. Sometimes I trance out into heady thoughts where the outside world gets blocked off.

I don't really know where meditation ends, naps begin, and where legit sleep falls in the spectrum. My goal isn't meditation though, my real goal is to black out cold, but haven't gotten there yet. So ymmv for anyone else attempting but it seems I'm in the same field as you describe.

Then I tend to naturally snap out of it before my alarm rings me awake.

Tools: travelers sleep eye mask, comfortable silent area (my car in parking garage), phone timer.
