Dreaming: an Introduction to the Science of Sleep

In Dreaming: an Introduction to the Science of Sleep, by Allan J. Hobson, he discusses the meaning of dreams. Some symbolize underlying meanings or so are wants that a person owns. Dreams have certain aspects that create a variety of emotions and responses which create diverse brain activity modes. He explains this when he states, “Dreams have specific perceptual, cognitive, and emotional qualities that set them apart from waking consciousness--toss of awareness of self, loss of orientation, loss of directed thought, reduction in logical reasoning, and poor memory--that correspond, as it turns out, to specific modes of brain activity.” Hobson shows the resemblance of brain chemistry and dream features.
I agree with Allan Hobson in the sense that I do think dreams represent an underlying meaning, but not always. Sometimes a dream is just a dream. Sometimes dreams give clues to what may happen. Sometimes I have dreams or reenactments of experiences whether they are positive or negative. Certain dreams mean different things.
