Not referring to lucid dreaming, which is simply controlling your dream. I’d like to know how to control what I dream the next night, regardless if it ends up as a lucid dream.

I remember reading a portion of a book then dreaming about it the day later. I am also aware of the “shifting” community (though they want to go to an entire alternate universe) in which they script throughout the day and sometimes get dreams related to it. Is there an actual practice for this sort of thing? Or is this something that happens only randomly?
