Sometimes people complain of having disturbing dreams with unpleasant images, despite leading a seemingly peaceful waking life. And so they wonder, "What is my unconscious mind trying to tell me?"

There can be several reasons for such dreams.

First, the dreams could be unconscious advice. Maybe in some way you are betraying yourself, forgetting something, or not fulfilling a potential. For example, persons on the edge of a midlife career change may have dreams about being in school and searching for a missing classroom, or they may find themselves in a class about to take a final exam while realizing that they completely forgot to attend the class all year. Thus the feeling of panic in the dream points to the real feeling of panic in their current life about the failure of their present career.
