Descriptions of dreams of women during pregnancy have appeared in the literature for more than a century. Daydreams and sleep dreams are differentiated. A review of the literature published during the last four decades uncovered a limited number of empirical articles. The general consensus is that the sleep dreams of pregnant women are indicative of their concerns regarding safety for self and for the expected child. The most recent information focuses on the use of groups to help pregnant women explore the content of their dreams.
