The second group of persons who are more susceptible than others to spirit interference are the mentally ill. Schizophrenia, organic brain disorders, and mood affective disorders may be associated with hallucinations. After reading Wilson Van Dusen’s, observations (chapter 11), one can see that mentally ill patients may be especially susceptible to spirit obsession or even possession.
This is not to imply that all psychiatric patients have spiritual infections. It is possible that most modern psychiatrists are correct in assuming that these people have hallucinations and other symptoms that are entirely internally generated. However, it is worth mentioning that several of Dr. Wickland’s patients were admitted to his institution with symptoms that would undeniably classify them as schizophrenics. They had been diagnosed by psychiatrists in other institutions as having “dementia praecox” which is a diagnosis no longer used but has been replaced today with the term “schizophrenia”. Today, schizophrenia is not considered curable, but the symptoms can be managed with modern psychoactive medications. There were no psychiatric medications in 1910. However, Dr. Wickland managed to literally cure his schizophrenic patients using spiritual means, and upon followup, they remained well many years later.
Even if a patient’s mental illness is not caused by organic brain defects or other “ordinary” psychiatric disorders, some mentally ill patients are just natural natural mediums or psychics that became mentally ill because of an inability to sort out earthly reality from spiritual reality. They could simply be psychologically unable to protect themselves from the lower order spirits that crowd around them. In other circumstances, these unfortunate people would simply become natural psychics or mediums. In any case, the mentally ill are certainly more susceptible to psychic infection than people who are not mentally ill.
