I have turned to meditation recently for those nights when I can’t sleep, and I feel it helps me. Nothing comparable to having slept well, of course, but it seems to ease my way forward during a few hours.
To be honest I’m not exactly sure if I should call it meditation. I just lie on the bed, or sit, eyes closed while I let my thoughts flow as freely as possible, getting to an quasi-dreaming state, where I experience images and sounds.
It’s the same thing I do when taking sleepless “naps”, with the difference of having a much more clear refreshing effect.
