FAQ
Q: What are hallucinations? A: Hallucinations are false sensory perceptions - experiencing something (seeing, hearing, etc.) that isn't actually present.
Q: Are hallucinations always a sign of mental illness? A: No, hallucinations can occur due to neurological conditions, substances, sleep deprivation, medications, and other medical conditions.
Q: Can hallucinations be treated? A: Yes, treatment of the underlying cause often reduces or eliminates hallucinations. Various medications and therapies are effective.
Q: What do auditory hallucinations sound like? A: They vary widely - from unclear mumbling to clear conversations, from single voices to multiple, and can be neutral, critical, or command in nature.
Q: Are visual hallucinations dangerous? A: They can be, especially if they cause fear leading to dangerous actions. Proper evaluation and treatment is important.
