Tell All You Know!: Which details are truly important sometimes can be hard to know ahead of time. A personal or family history of trauma, previous hospitalizations, drug use, psychiatric hospitalizations or treatment, should all be discussed. Also, specific illnesses like bipolar disorder, schizophrenia, depression, etc. Are important, because hallucinations can have many causes ....Drugs, genes, trauma, etc.
