Hi, im new to lucid dreaming and i was wondering how voice commands work. Do you kinda just yell what you want to happen? For example you want a car, do you yell CAR! or do you have to immagine its there and it will appear. Also, is it possible to completley change a dream? For example: you are at school, but you want to be on a pirate ship fighting pirates, do you just think about that? or do you have to pre-meditate what you want the night before?
