Many dreams lead us to feel an intensity of emotion we may seldom if ever feel in waking life. If the emotions felt are frightening or disgusting we call the dream a nightmare. One of the common features of a nightmare is that we are desperately trying to get away from a situation; feel stuck in a terrible condition; or on waking feel enormous relief it was just a dream. Because of the intensity of a nightmare we will remember it long after other dreams; remember even if we seldom ever recall other dreams, even worry about what it means.
