Auditory hallucinations are experiences where individuals hear sounds, voices, or noises that are not present in the environment. These sounds can vary in nature, ranging from simple noises to complex conversations. They often occur in people with mental health conditions, such as schizophrenia, but can also be associated with depression, bipolar disorder, or substance use. The exact cause of auditory hallucinations is not fully understood, but they may result from changes in brain activity or chemical imbalances. Treatment options include therapy, medications, and support from mental health professionals to help manage symptoms and improve quality of life.
