you could turn those same fantasy's into art, by either writing a story about them, or maybe drawing a comic, painting the scenarios, etc.... if you're new to any of these art forms, don't expect them to look like what's in your head your first go around, keep in mind these skills take time and practice. but it's so satisfying putting them down on paper

Art comes in very different forms. Try every you can reach and you will find one you are most comfortable with. Absract style was created exactly by people that couldn't truly find form of their emotions. That's okay not to know for sure.
