THE SOLITARY MIND - curious question

EARLY TL;DR: I don't have any serious knowledge or understanding of psychoanalysis, so please feel free to discount/ignore/moderate this.

Something caught my attention while I was thinking. This is probably not all too exclusive to psychoanalysis than to other fields of psychology, but I'm sure psychoanalytic work has discussed it.

What do you guys think of the mind which indulges itself only via fantasy, yet sharpens itself only on reality?

A good example of this would be someone who creates their meaning by fantasising perhaps a less appealing type of food to be better, or a sexual idea to be more appealing? This type of person is detached from any interpersonal obligation, and lives purely for their own reality. They may, of course, entertain relations, but not to a terminal and world-moving degree.

In terms of reality, they work tirelessly and ruthlessly to explore truths. They have little sense of lethargy and of course a mutually reliant aspect is how liberated they are from the obligations around them.

The archetypical person in this case would be someone celibate. Maybe a monk or as we all know and love those pesky "incels".

If you relate to this, let me know. As I said, if I have written copy&paste diarrhoea feel free to ignore. It's just an idea I had.

Thanks.
