In mild I know that you have to set your intention to something before going to sleep, either in the morning or at night. And to do this you use visulization and auto suggestion.

But what is it best to set your intention to?
Realizing that you are dreaming?
Remembering that you are dreaming?
Reality checking?

And what mantra do you use?
I used (the next time that I am dreaming, I will realize that I am dreaming)
