reoccurrence of the delusion that she can control the behaviors of
others through her breathing and that people can read her mind. She
is convinced that she is being watched, followed, complains of being
confused and at times may repeat phrases without meaning to
others. She admits to hearing threatening voices stating that they will
kill her for having the power to hurt others. She lacks motivation and
hesitate to participate in social activities due to increased paranoia
that everyone around her know her thoughts and the power she has
to read minds.
