As far as auras, the same is true for those who have epilepsy, as sometimes the precursor to a seizure episode is an aura, be it visual, tastes, and smell. (my son had unrelenting seizures in his early childhood years). This is an area that may be useful to look at as certain seizure foci in specific regions of the brain may indeed induce hallucinatory effects leaving the individual with the sense of "loss time" phenomenom. (Seizures come in different forms not just the classic Grand Mal, tonic/clonic form)
Extremely busy last night, hopefully quieter this evening to do a meta search on the psychology journals.
Again, thanks for the new thread!

Tim Hebert wrote:In the Old Testament, its last book is that of Malachi. One could say that Malachi was the last Old Testament prophet. God never directly speaks to Malachi. Malachi's quotes are from the past prophets, yet Malachi forms the pattern: When times are tough and man has fallen, yet again, away from God, there arises one individual who is the oracle to warn the flock back into the fold. BTW, the last time that God is directly quoted from in the Bible is that from the Gospels when John baptizes Jesus in the Jordan. There after, God never utters a word. I've read most of the ancient Christian writings and this still appears to be true. Why is that?

“[T]he percipient, while experiencing the hallucination, is at the same time normally perceiving real objects within his range of vision, and the hallucinatory percept is brought into relation with these, so as to occupy apparently as definite a place in the field of vision. The phantasm appears to stand side by side with real objects. “
“The Induction of Anomalous Experiences in a Mirror-Gazing Facility: Suggestion, Cognitive Perceptual Personality Traits and Phenomenological State Effects
Previous research suggests that mirror-gazing is efficacious for the facilitation of anomalous experiences. The present experiment tested the hypothesis that the incidence of such experiences is a function of the demand characteristics of the procedure. Participants were randomly allocated to one of two conditions and completed a battery of trait and state measures. Individuals who were given suggestions for anomalous experiences, relative to those who were not, reported a greater number of visual, and a suggestively greater number of vocal, hallucinations. The experience of a descriptively dissociative phenomenological state was the strongest predictor of the reporting of anomalous experiences, but only correlated with the experience of anomalous perceptions in the suggestion condition. Experients of visual apparitions were found to significantly differ from nonexperients in their preference for a visual cognitive style independently of condition.
A review of the literature indicates that a great deal remains to be learned about the possible neuroanatomical and neurophysiological correlates of hypnotic and dissociative states. However, there does seem to be accumulating evidence that hypnotized individuals have an unusual ability to modify neurophysiological processing of perceptions. Electrophysiological and neurochemical evidence suggests special roles of the frontal and temporal lobes. Brain imaging research suggests that hypnotic concentration involves activation of centers in the anterior cingulate gyrus and the right frontal lobe. It is concluded that hypnosis may prove to be a useful window into the brain basis of mental events. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Why people see things that are not there: A novel Perception and Attention Deficit model for recurrent complex visual hallucinations
Abstract
As many as two million people in the United Kingdom repeatedly see people, animals, and objects that have no objective reality. Hallucinations on the border of sleep, dementing illnesses, delirium, eye disease, and schizophrenia account for 90% of these. The remainder have rarer disorders. We review existing models of recurrent complex visual hallucinations (RCVH) in the awake person, including cortical irritation, cortical hyperexcitability and cortical release, top-down activation, misperception, dream intrusion, and interactive models. We provide evidence that these can neither fully account for the phenomenology of RCVH, nor for variations in the frequency of RCVH in different disorders. We propose a novel Perception and Attention Deficit (PAD) model for RCVH. A combination of impaired attentional binding and poor sensory activation of a correct proto-object, in conjunction with a relatively intact scene representation, bias perception to allow the intrusion of a hallucinatory proto-object into a scene perception. Incorporation of this image into a context-specific hallucinatory scene representation accounts for repetitive hallucinations. We suggest that these impairments are underpinned by disturbances in a lateral frontal cortex–ventral visual stream system. We show how the frequency of RCVH in different diseases is related to the coexistence of attentional and visual perceptual impairments; how attentional and perceptual processes can account for their phenomenology; and that diseases and other states with high rates of RCVH have cholinergic dysfunction in both frontal cortex and the ventral visual stream. Several tests of the model are indicated, together with a number of treatment options that it generates.
Content analysis of published accounts of 40 anomalous experiences reported by anthropologists allows qualitative evaluation of elements within evolutionary theories pertaining to religion .The analysis supports findings from previous studies indicating that certain anomalous experiences have cross-culturally consistent features. Narrative and structural features within the anthropologists' accounts coincide with those gathered in northeastern North Carolina and many other areas. The data also reveal the capacity of these episodes to transform belief, supporting an experiential source theory regarding faith in spirits, souls, life after death, and magical abilities. The narratives indicate that anomalous perceptions cause some anthropologists to consider novel theories. This study supports evolutionary explanations for the origin of religion and provides predictions regarding research directions in anthropology.

Luck wrote:Tim,
I had an insight. I have been prone to migraines and frequently see auras before they occur. I did a quick search and a small percentage of migraine sufferers do experience auditory and/or visual hallucinations. Don't know if the mechanisms are similar but migraines can occur due to stress. This may provide another avenue of exploration for you.

Luck wrote:I came across this rather interesting paper that asserts that visual perception and hallucination belong on the same continuum. According to the author, perception is subjective and can account for the occurrence of false images. He does identify some other studies such as the study of blind spots in vision with the normal population (which may give some additional useful information). If I understood correctly, the hallucination occurs in the processing of the visual data. I don't think this is out of line with Jaynes and could provide a mechanism for anomalous visions. This was actually a philosophical paper, but there may be psychiatric research along these lines.

Delusions (and hoaxes) are much more likely IMHO. Why do people start to hallucinate is a mystery but I doubt they are "entirely unpredisposed" (to name a text by Martin Kottmeyer). Very often they have a history of less known (or even hidden) encounters with the paranormal, before or after the main event that lands them in the UFO books. Some ufologists purposefully ignore or downplay this aspect, to make the "alien" encounters more compelling.
Tim Hebert wrote:The following was introduced while looking at various ufo phenomenon theories on the ufoiconoclast blog. Jose Caravaca has been formulating a theory called "The Distortion Theory". Rather than describing it my self, I have the following link to his original premise. The rest of his site is devoted to further investigations to support his theory. Its very interesting to say the least.
About 11:00 am in the morning, Mr. Simonton heard something like the sound of "knobby tires on wet pavement."
Jacques Vallee, in his book Passport to Magonia, compared this "culinary gift" with the food of the fairies which does not contain salt.
