However, a group of Scandinavian scientists say they have evidence that hypnotic trances are a real and unique state of consciousness, which cannot be imitated or faked by the non-hypnotized, and which (at least some) hypnotists can activate and deactivate at will using a one-word cue. So be careful out there. Nano Patents and Innovations writes:
A multidisciplinary group of researchers from Finland and Sweden has found that strange stare may be a key that can eventually lead to a solution to this long debate about the existence of a hypnotic state.
One of the most widely known features of a hypnotized person in the popular culture is a glazed, wide-open look in the eyes. Paradoxically, this sign has not been considered to have any major importance among researchers and has never been studied in any detail, probably due to the fact that it can be seen in only some hypnotized people.
