The English magazine "Fortean Times" is always a source of articles which make me think. Another fascinating article appears in the March 2012 issue (pp56-57) penned (or typed) by one Rob Gandy.
A management consultant, Gandy, had an unusual experience in December 2006, which he shares with us. After working on bicycle repairs, then talking to his wife, he lost a portion of his memory for recent events. At first, his wife thought he had experienced a stroke. However, the diagnosis was Transient Global Amnesia (for more click here.) His memory slowly returned.
Gandy points out that a FT contributor, Gail-Nina Anderson, who also had a TGA episode, joked that "...if she had been on a dark lonely road when she experienced TGA, she would have been able to attribute the time lapse to aliens."
Gandy then writes "A stereotypical; event in ufology is that someone is driving through the countryside at night when their car enters a luminous cloud, or similar; then the driver finds himself miles down the road with half an hour missing."
"A number of commentators have argued that many, if not all, perceived UFOs are actually forms of a rare meteorological phenomena. Therefore, my speculative interpretation of these events is that they do involve rare meteorological phenomena and these phenomena can induce TGA in humans who get too close to them."
What is the frequency of TGA?
"Estimates...varies from a minimum of 2.9 cases per 100,000 population (Spain) and 5.2 per 100,000 (USA); but among people aged over 50, the rate of TGA incidence is reported to range from approximately 23 per 1000,000 (in a US population) to 32 per 100,000 (in a population in Scandinavia.)"
Gandy argues that some people who have a TGA episode, might arrive at an interpretation of an alien abduction, in their world view.
"I surmise that most, if not all, reported episodes of lost time are not, "lost time: but "lost memory," and suggest that there are rare meteorological phenomena that can induce memory loss on a temporary basis."
I find the meteorological part of Gandy's hypothesis a bit of a stretch. Why do we need a rare meteorological phenomena to cause a TGA? TGA's happen to some people, in a variety of circumstances.
I do however, think that TGAs may have an involvement in some UFO encounters. Just as hypnagogic and hypnopompic imagery; (click here); fantasy proneness; (click here) sleep paralysis (click here for a detailed article by Keith Basterfield) ; migraines (click here); false awakenings (click here) and other conditions seem to be involved in some encounters. TGAs may account for element of some such events. Perhaps, many abduction accounts may involve one, or a combination of these triggers?
