So in my normal dreams, I fly alot. But the way i fly is a little weird. I start to jump then start swmiming in the air! And I was wondering if I could do that in my lucid dreams. 'Cause it is pretty fun (although pretty slow).
Moved from General Lucidness. 
If in a lucid dream, you want to, or imagine it, you will. Anything you can and can’t do could be done in a dream. If you become lucid, remember the way flied, picture it, and do it.
Of course you can 
the only limit in your LD’s is your imagination.
Just take off and explore all the beautiful places of your dreamscape ^^ you can take this topic for reference of faster ways of flying, as air-swimming tends to be pretty slow.
Good luck
