Kind of offtopic to this board, but here it goes:
I don't think I've ever tried to do it intentionally, but usually you just realize you're dreaming due to some events which your mind registers as inconsistent, or you simply
know you are dreaming, at that point you can do whatever you want, but it can be tricky not to wake up if you get overexcited. However, there are many times for me when, I don't really realize I'm truly dreaming, but I still do whatever I want, no matter how unrealistic/unnatural/disobeying the laws of physics/etc those actions can be. Realizing you're dreaming can free you of some inhibitions you manifest in your dream, but if you don't have them to begin with, it doesn't really matter if you're realizing that you're dreaming or not, as you can already do anything you may want.
