Hidden Observer Theory
The hidden observer theory by Ernest Hilgard assumes that a separate consciousness is formed in an individuals mind during hypnosis which is capable of observing the individual. This hidden observer during hypnosis is able to observe themselves and their pain without having to directly experience any negative feelings themselves. Patients who are being analgesically hypnotized and are 'under' reporting not pain when asked if a hidden part of them could feel their pain. After the patient was asked about the hidden observer the patient begins to report pain.
