Okay...I think I have everything set for the first time I try this...but I have some questions.

First....lucidity and reality checks. When you start the dream, do you wake up in your bed where you fell asleep? Or do you just get up and go through your daily routine before noticed that you are dreaming because you have a purple dog, and then you gain control?

Second...how long do they last? And is it possible to alter people with practice, like if I wanted to be taller?

Thanks in advance...
