Hmmm this sounds fun:
1: I would have to say being with my dream guide, which has only happened once so far but I am super excited for more, it was such a satisfying experience.
2: Elemental magic, the very first thing I did in my first lucid dream was shoot a stream of fire from my right hand and lightning from my left.
3: Doing funny stuff with my body, pushing my fingers through my palm and looking at my reflection (or lack thereof last night) is pretty cool.
4: Flying, I haven't managed it yet, keep on forgetting, but I really want to do it.
5: Fun time, you know what I mean hehe.
