Seek professional care if you experience any of the following symptoms
Generally, Hallucinating can be related to:
A psychotic disorder characterized by disturbances in thinking (cognition), emotional responsiveness, and behavior, with an age of onset typically between the late teens and mid-30s. Hearing voices and/or believing things that aren't consistent with reality are common symptoms. The exact cause is unknown, but a mix of genetic, psychological, and environmental factors are likely responsible.
Dissociative disorder is a mental disorder that involves experiencing a disconnection and lack of continuity between thoughts, memories, surroundings, actions, and identity. People with dissociative disorder escape reality in ways that are involuntary and unhealthy, causing problems with functioning in everyday life.
Herpes Simplex Encephalitis (HSE)
Herpes encephalitis is inflammation of the brain caused by the herpes simplex virus, resulting in neurological symptoms.
Sometimes, Hallucinating may be related to these serious diseases:
Wernicke encephalopathy (WE) is an acute neurologic condition condition characterized by vision changes, ataxia (loss of coordination and balance), and confusion. It is caused by B1 or thiamine deficiency.
Posterior Reversible Encephalopathy Syndrome (PRES)
Your doctor may ask these questions to check for this symptom:

Male, 50s
The questions asked and possible causes seemed spot on, putting me at ease for a next-step solution.

Female, 40s
I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
