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 of being pursued or attacked, late or unprepared for a presentation 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.
