Yep. I could be reading a book and intending to finish the chapter I’m on and suddenly it’s 4 am and I’ve read 6 more chapters and about 100 pages to go so I might as well finish it. Also applies to watching a show or playing a game.

Same, just lying down in bed won’t do it. I have to exhaust my brain first, then I can sleep.
