Tangentially, it's one of the reasons why I'm still using an older iPhone for my daily life because the haptic Home button (which was removed in newer models) makes it easier to use in an half-asleep state whereas I end up tapping on things accidentally when using my 13 Pro in that state: that button is the escape hatch, like ESC on a keyboard.
Any friction between the time I have an idea and the moment I can capture it increases the risk I will forget it before I have time to write it down.
I think capturing ideas is lame. It delays thinking of more of them. The benefits of thinking to oneself come not from a single idea, but from the compounding effect of all of them. And you're not thinking of your next idea while you're wasting time capturing the last one.
It's better to let your mind wander to maximize the compounding effect between the ideas, rather than to fret about memorializing every vainly appealing thought (and btw, I bet if you did that while sober, it would look just as ridiculous when reading it the next day).
Just let it flow, man. You'll remember the good stuff.
