  • see things that are not there like objects, shapes, people or lights
  • feel touch or movement in your body that is not real like bugs are crawling on your skin or your internal organs are moving around.
  • smell things that do not exist
  • taste things that only you feel are not pleasant or is strange
  • think that your body is moving like flying or floating when it is not

They can also be caused by an infection, brain tumour or confusion (delirium), especially in older people.

Treatment for hallucinations

Treatment for hallucinations will depend on what's causing it.

For example, if you have a mental health condition like schizophrenia, you may be given therapy or medicine to help reduce your hallucinations.

A GP may recommend lifestyle changes like drinking less alcohol, not taking drugs and getting more sleep to reduce your hallucinations.
