Honestly, I day dream allll the time, which is pretty bad in certain situations when I need to be focused, but I tend to remind myself of the importance of what I should be doing at that time, it usually does the trick for a while. But no, I don't find day dreaming to be an issue. Like you said, it's somewhat enhancing. I'm a creative type (music, art, film, etc) and I swear to god, most of my concepts would come from day dreaming throughout the day. Just some random inspiration that would flutter through the mind and I'd just have to write down or record right then and there if I could. I think day dreaming is absolutely normal, and again, a good thing. Back before all this technology, we had no choice BUT to day dream as a source of learning, entertainment, experimenting, etc. That's still a part of our human nature, and thank jeebus it is. I'm not sure what your passions are, but they're most likely reflected in the content of these moments. You should pursue where they point you. No matter how impractical it may seem. ....but I digress. I have this, but sure as hell don't see it as a problem.
