Almost everyone has experienced one or more dreams that contain anxiety or outright fear. For some, unpleasant dreams or nightmares recur repeatedly; for others, the content may change while the theme remains the same, such as scenes of falling,or an exam, stuck in slow motion, unable to move or scream , to name a few common themes. This type of experience, when unpleasant, is usually associated with lack of progress by the dreamer to recognize and solve related conflicts in life.
