Those studies you cited are dealing specifically with memories of trauma that happened years ago. I'm talking about trauma that has just happened. And false memories of trauma that has just happened doesn't happen. Recent traumatic experiences are always much stronger and more indelible than normal experiences. This is just common sense and basic science. And it's the reason for PTSD, where victims of trauma continue to experience the memory of their trauma just as vividly as if it just happened. And when thousands of people report the same traumatic experience of being abducted by aliens, then it's much more likely it was real than a false memory they just made up. And in the OP the three women reported the same exact experience. They are not going to have the same memory if it is just a false memory.
"In a recent New York Times op-ed, one psychiatrist wrote, "Neuroscience research tells us that memories formed under the influence of intense emotion are indelible in the way that memories of a routine day are not." Dr. Ted Huey, a professor of psychiatry and neurology at Columbia University, agrees with that assessment of memories.
Huey told "CBS This Morning" there is a misconception that emotion and trauma are bad for memory. But he explains, "The way our brain tags what's important to be remembered is emotion."
An example of this phenomenon would be that most people can clearly remember the morning of September 11, 2001 – an emotionally charged day for most – but have no clue what they were doing the morning of September 8, 2001."
"If an event elicits an emotional reaction in us, then it's more likely to make it into our memory. "Things that have more emotional significance tend to get more encoded," he says.
And when something elicits an intense negative emotion, like a trauma, it's even more likely to be encoded in the brain.
"The stress hormones, cortisol, norepinephrine, that are released during a terrifying trauma tend to render the experience vivid and memorable, especially the central aspect, the most meaningful aspects of the experience for the victim," says Richard McNally, a psychologist at Harvard University and the author of the book Remembering Trauma.
That's because a high-stress state "alters the function of the hippocampus and puts it into a super-encoding mode," says Hopper, especially early on during an event. And "the central details [of the event] get burned into their memory and they may never forget them."
Regarding owls remembered during abduction experiences, these are alleged to be examples of "screen memories, images psychically implanted in the mind of the abductees to cover up the real alien memory. See:
