As many of you know, my husband Gary is a master of lucid dreaming. I frequently wake him up in the morning, have a conversation with him, and then he goes back to the dream he was in and finishes the dream. I. Find. This. Freaky.
Now, he has decided that instead of surfing his subconscious and riding whatever dream wave that arrives and picking it up again later, he's going to govern what he dreams about, because why not? If you can dictate that you're going to "finish" a dream, why not say that you are going to "start" a dream?
So I imagine he bored himself with sex dreams for a while, and now he's using his freakish dream powers for self-reflection. He has decided that every night he's going to tell himself to dream about his childhood, and see what happens. I assumed that he would dream about things like "that time aliens came to junior high with buckets of KFC," and I could laugh at him, but he's actually been remembering things from his childhood. Then he looks at them from an adult perspective and revises his opinions.
It's like a superpower.
