I can only speak to my experience.

Often I fall back to films or games I’ve already developed an emotional attachment to. Because the mental energy it takes to develop a new attachment is significant. I find I can trick it by putting something on while I do something else and then come back to watch or listen to it later where it’s already somewhat familiar.

My ADHD doesn’t really let me have long term (hour plus) focus easily. It wants the easy dopamine hit from something that it knows it already can drop into.
