describe detective deweys dream, does it turn out to be accurate?

Dewey is having a nightmare. He walks into a cafe and sees the killers. They leap through the plate glass window and he chases after them. He wakes up in his office. As he gets ready to leave, he gets a phone call. It is Nye, reporting that Dick Hickock has been writing checks all over Kansas City.

The narrative is written in a way that makes the reader sympathetic to Dick and Perry's situation. While Perry is waiting in the laundromat, worrying about being caught by the police, one both looks forward to and dreads his eventual capture. Now, as what was a mystery becomes a manhunt, the suspense becomes less cerebral and more physical. Just as Dewey dreams of chasing the killers down the street, so does the reader imagine what the confrontation between Perry and Dick and the KBI will be like.
