I was lucky enough, when I was younger, to have the chance to do as much as possible, and I found what I wanted to do. I did swimming, gymnastics, kickboxing and the one that took off more than the others was acting.
I don't really know what the dream role would be. That's a hard question to answer. You never really know, until you're immersed into something, how passionate you feel for it and how it unravels.
