I mean, I legitimately struggle to sleep without the disengagement.
On the very few times reading hasn't worked for me, I have to very purposefully and intentionally think of ridiculous things that are completely unrelated to my life. One that works quite well for me is thinking about animals in formal attire... so I'll try to visualize a cheetah in a tuxedo or a giraffe in a ballgown and before I know it... I'm waking up in the morning.
Me too...I'm struggling at the moment actually. My job is, well, let's say it's all-encompassing and has a voracious appetite, and I sometimes struggle to detach enough to find a restful sleep...often up at 2:30 and start to think and that's the end of sleep for the night. It's a problem.
I'll try cheetahs in tuxedos and ballgown attired giraffes and see how it works.
