For example, I enjoy dreaming up scenarios to write about in fiction books. I have one involving a punctuated equilibrium of evolution in humanity induced by a meteor strike, one involving an alien wild west figure who's anatomy alone provokes interesting twists on the physiology of traditional western mythos, etc. I think the thing is that it cannot simply be a story. There have to be conceptual notions buried within the story that makes the effort worthwhile. I could never read, for example, a book simply for superb narrative. I have to feel there are some underlying contextual happenings to be drawn to the surface that makes my mind toil in order for me to enjoy my experience. Incidentally, I tend to read/watch/listen to the same media over and over again, because I'm selective about what I'll entertain, and these selections are usually intentionally rich in meaning, capable of extraction multiple times over.
Also, growing up, I would study current scientific trends, like quantum computing, imagining what future uses will spawned from it. I dreamt up a quantum radio one day, for example.
So yeah, I'd say I enjoy using my imagination, though perhaps to an external observer, I'm very "contained" - hence the suppression of intuition Jung spoke of. This is my interpretation though, of course. I'm curious to see what others have gotten from the data.
