Hi there, and welcome.
Many people dream 'movie dreams', my wife claims that most of her dreams are like that.
Lucid dreams are best when you can be in a body of some sort, but there's some tricks to 'possess' a body if you need to

So are you learning lucid dreaming to combat nightmares?
As a kid, I naturally started lucid dreaming in order to fight my nightmares (just happened when something tried to hurt me)
Lucid dreaming really does help nightmares, and you'll find that the fear/worry/phobia behind the nightmare will become better by combatting it in your dream.
At least that's what happened to me - I don't have nightmares like that anymore.
