Hallucinations and hearing voices
Hallucinations happen when someone sees, hears, smells, tastes or
feels things that don't exist outside their mind. They are common in people with
schizophrenia, and are usually experienced as hearing voices.
Hallucinations can be frightening as they may be unexpected or unwanted, but
there's usually an identifiable cause. They can occur as a result of taking
illicit drugs or alcohol, or as part of a mental illness such as schizophrenia.
Some people may experience hallucinations that are not related to a mental illness.
If you have hallucinations and are worried about them, see your GP straight away. If necessary, call 999 as you may have a serious mental health condition.
Hallucinations can make you feel nervous, paranoid and frightened, and it's important to be with someone you can trust.

Hallucinations can also occur as a result of extreme tiredness or recent bereavement. However, these and other rarer causes are not covered here.
Hearing voices is a well-recognised symptom of schizophrenia, dementia or bipolar disorder, but can be unrelated to mental illness.
The experience is usually very distressing, but it is not always negative. Some people who hear voices are able to live with them and get used to them or may consider them a part of their life.
It is not uncommon for recently bereaved people to hear voices, and this may sometimes be the voice of their loved one.
There is no shame in seeing a psychiatrist, and it's important to be thoroughly assessed and treated early. If your voices are due to schizophrenia, the earlier your treatment is started, the better the outcome.

Hallucinations caused by medications can be dose-related and usually go away when you stop taking the medicine. However, never stop taking medication without speaking to your doctor first, and if necessary after being assessed by a psychiatrist.
Speak to your GP about how the medication is affecting you, so you can discuss the possibility of switching to another medicine.
You may hallucinate sounds or see things that don't exist, such as moving objects or even a formed image such as a person (people may think they've seen a ghost).
Hypnagogic and hypnopompic hallucinations are especially common in people with the sleep disorder narcolepsy, although they are also common in people without this or any disorder. They are essentially like dreams, and in themselves are nothing to worry about.
In the meantime, stay calm, keep your child cool and reassure them. Encourage them to drink plenty of fluids and give them paracetamol or ibuprofen (always read the patient information leaflet to find out the correct dose and frequency for your child’s age, and check they are not allergic to medicines you give). The hallucinations should pass after a few minutes.
