Honestly I've been doing this for my comic and I thought I was just going crazy from isolation XD I feel scenes, and what the characters feel, and each action has a sort of rhythm to it, so it's easier to dice up into panels. It all plays like a movie in my head, so I often get camera angles, gestures, expressions, sounds, touch, music, and vivid emotions. Some scenes are fuzzier than others, but the more I replay them the sharper they get. It's like a really vivid dream.
Writing and drawing are just like acting, but onto someone else. How would you make your audience feel something if you don't feel it yourself? Gotta respect creators with aphantasia, I can't imagine what that would be like! (lol irony!)
