i'm new to all this yeah

and i was just wondering when you people talk about others that were "born with the ability to lucid dream" or are natural lucid dreamers,

to what extent do they have control over their dreams? Just like fall asleep and realize 100% of the time that they are dreaming and when they feel like changing something, they just say Gimme a dog and a dog appears effortlessly? : |

or does it just mean they get a lot of lucid dreams but not like 100% effortlessly and 100% any time they feel like it.

tyTy : )
