If you are talking about auditory hallucinations, most people with schizophrenia hallucinate voices commenting on their actions.
There are different forms of schizophrenia. the most common symptoms of the disorder are visual and or auditory hallucinations. These are very difficult for the patient to sort out, but medications can be very helpful.
Auditory hallucinations during schizophrenia can be perceived as either out loud or inside of the head.
Schizophrenic hallucinations can be either. However, most schizophrenics report predominantly or entirely auditory hallucinations.
They were admitted because they pretended to have had auditory hallucinations saying "empty", "hollow", and "thud".
Hearing voices in ones' head when no one is actually talking is known in medicine as an auditory hallucination. These auditory hallucinations can take on many different forms. Sometimes, the voices are indistinguishable from each other, and can be numerous. Often, the voices are heard clearly to say demeaning and derrogatory things about the victim of these hallucinations, and are then called persecutory auditory hallucinations.These hallucinations are one of the hallmarks of the condition known as psychosis, and can indicate an underlying psychiatric disorder like schizophrenia. The sufferer of such auditory hallucinations should seek a physician's help as soon as possible.
Schizophrenia is a scientific name. Schizophrenia is a mental disorder characterized by a disintegration of thought processes and of emotional responsiveness. It most commonly manifests as auditory hallucinations, paranoid or bizarre delusions, or disorganized speech and thinking, and it is accompanied by significant social or occupational dysfunction.
Auditory hallucinations alone (unless they consist of a voice constantly commenting on everything you do or two or more voices conversing) are not enough for a diagnosis of schizophrenia.
It depends on the severity of the disease and medication; everybody hallucinates when they sleep, that is dreaming, so strictly speaking anything is possible. Most common however are auditory hallucinations (hearing voices, sounds), and hallucinations of movement in peripheral vision.
Usually hearing voices is a sign of hallucinations which is a sign of mental illness. If you are hearing voices externally then these hallucinations could be signs of schizophrenia. See your doctor, it could be serious.
Auditory or visual hallucinations are intense, sometimes terrifying experineces at the beginning or end of a sleep period.
If the person was born totally deaf, then no, they would not hear voices, because they would have no concept of what a voice sounds like. They would exhibit other symptoms of schizophrenia, that do not involve sound.
