I’d say my imagination varies. There’re times where my imagination is so vivid that I get lost in my mind and aspects such as mental visualization and sensations are as clear as tangible reality. Then… there are times where my imagination is faded like a age-worn photo, which really becomes frustrating because I practically live in my head… which can really become a bad habit.
On a regular day, my sense of taste is the best - no falter. I can imagine it with such clarity that it actually feels as if I’m, not only tasting, but eating something. It never satiates my hunger, though…
Touch is just below taste. Basically, if I can imagine it, I can feel it. It isn’t limited to simple, neutral texture-style touch, but pain and pleasure also - such goes for emotions, too. I may have more trouble with my “erogenous zones,” but with enough concentration and can emulate/simulate a feeling.
With smell, I get almost absolutely nothing. It takes considerable concentration to reproduce even the faintest scent.
Speaking visually and auditorily, that’s where my imagination fluxuates most, and often. Not so much in mental sound as in mental sight. I do notice that I can “see” in my mind’s eye with my physical eyes open as opposed to closed. The only time the clarity when closed reaches that of open eyes, or even physical reality, is when I’m in HI or dreaming. I do realize, however, that some people have trouble visualizing even beyond shapes and colors, or simple objects. I speak of much more complex imagery.
(I read somewhere, though - maybe even here - that reading more often can help to improve mental imagery…)
Overall, though, I’d say my imagination is pretty good.
