Hi Grace,
Evenings and screens are a bad mix for my dreams too. If the two are close together, I either spend hours not really sleeping but going over the same material on and on for hours, or I get a bunch of vivid dreams, as you describe. This is probably my most difficult thing to overcome at present as the evening is a time when I can get on with some typing and also a time when good ideas bubble up but I shouldn’t push it too close to my sleep.
I do like your following impulses idea. Sounds very helpful!
