"Freud's most famous and important claim was that "wish-fulfillment is the meaning of each and every dream." Although this hypothesis was based on his work with adult patients, he began his argument with several simple wishful dreams that he overheard from his pre-school children or learned of through the parents of the dreamers. However, a five-year longitudinal study in the sleep laboratory of 14 children ages 3-5 reveals on the basis of dozens of awakenings that young children have static and bland dreams, not at all like Freud's anecdotal examples (Foulkes, 1982; Foulkes, 1999)."
