The Dreaming Walls begins when the young couple, after returning home from vacation, finds the corpse of a strange-looking man on the floor. When the police arrive, the corpse is no longer there, and nobody knows what happened to it.

From that moment, the family members start having nightmares. Who are black and white harpists? What fate awaits the heroes of the novel? You will have to find out for yourself.

At first glance, Krzysztof Maciejewski's book may seem like a simple ghost story - we have a haunted house, strange things are starting to happen, and we need to solve the mystery.

In fact, Dreaming Walls is far from this type of novel. In each subsequent chapter, the author leaves the reader with hints that indicate that not everything is what it seems.
