 Deirdre says, by the way, the reason this works is that your dreams are informed by the experiences, emotions, places, and people that you've encountered in your waking life. You can use dream incubation for other things too. Like if you're having a nightmare over and over, you can try to change the dream by coming up with an alternate ending during your waking life. And then every night as you're falling asleep, you'd be saying the simpler version of, if the nightmare starts tonight, I want it to take this other path.
