I counted. There are six artifacts that directly relate to dreams. The others in the sleep section mostly affect sleeping, insomnia, or passing out.

The artifacts the deal with dreams are Ann Faraday's Jacket, Carl Jung's Cuckoo Clock, Francisco Goya’s “The Sleep of Reason Produces Monsters”, Marie-Jean-Leon Lucoq's Memento Mori, Sigmund Freud's Marble Tablet, and Wes Craven's Freddy Kueger Glove.
