A dream is one thing, but a dream about a dream?

These crawdads in Portland, snapped by Mush and Smiling Bill, have absolutely nothing to do with the dream The Great Plotnik had last night. Something happened in this dream that he has never had happen to him before.

He's riding his bike along a city road, and a police car cuts him off. The cop (hmmm, not wearing a police uniform) tells him he's wanted for murder. Plot asks him what he's talking about and the cop tells him. But here's the strange thing: the crime the cop is talking about actually occurred in ANOTHER dream that Plotnik had several years ago, a vivid and frightening dream at the time, in which Plotnik, cornered by some villain as always, was forced to bury someone in a pit and cover him up, hoping nobody would find out.

Now, the cop in the new dream knows about Plot's old dream. What in the world is going on here?

Does this mean that not only is everything we ever do stored in our brains, but even the dreams we dream? Does this mean that old dream has been on Plotnik's mind for years, even though he had forgotten about it? Has this ever happened to anyone else?

And what does any of this have to do with crawdads?

The Great Plotnik will probably find out tonight when he dreams about riding his bike and being cut off by a plate of crawdads. Yumm. He hopes he dreams lemons.
