Lots of people know things deeply in their subconscious that they are fully ignorant of in their conscious thinking. These can manifest as gut feelings, or anxieties, and with therapy, can be identified. Things like "you should leave him", or whatever.

Yup. My daughter (15y) had the perfect example this morning. She said she was thinking about shooting a person with a cannon upwards, then realizing they feel effectively zero gravity at top, and maybe this could be usefull. Then she remembered parabolic flight paths to train astronauts, realized it’s the same thing, and that she started wondering about a thing she already knew.
