Note

  • Hallucinations can lead to incoherent speech and delusions, such as feeling that everybody is out to hurt you or thinking that you are living at an earlier time of your life.
  • It may be useful to focus on how the person feels after when they are hallucinating (frightened, happy, or sad) rather than trying to prove them they are hallucinating.
