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, or naked in public, 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.
