On Deja vu. (Random thought, what's yours)

[camstory]

Below is a random thought I had on Deja vu. It may get some play, or not, but I may come back to this thread with other random thoughts too long for daily thoughts. We don't have a good random thoughts thread I can think of? So any random thought will work here, does not have to be about Deja vu necessarily.

OK, there may be reasons why this idea just does not work, and it is very simplistic which is nice in two ways - I don't have the education to work out complex ideas when it comes to things like the brain, and b/c simple ideas are often partly right b/c of their broad scope.

OK, lets say the feeling of what is in our computer/brain is tagged with a track that gives us the sense of what is in the present/real time. So everything coming in in real time carries the tag 'happening now' and it is passed to memory where it is tagged 'from past'.

What we know about memories is that when they were recorded with high enough detail (HD mode) that when recalled fully it is fuller than other low def memories. These memories are rare. Sometimes these high def memories when recalled even cause muscle reflexes, facial expressions, audio images repeat, etc, of the time it happened. These memories are always recorded during a time when the brain is in a state of high awareness. Like when getting shelled, or when caught in a place that could be fatal. These are the memories that torment ppl with ptsd.

What we also know is that when ppl are asked to think about the piece of Deja vu that feels like memory they say that it seemed so real, so vivid. A memory stronger than most memories, - most memories, common memories, low def memories, are recalled with much of the original detail missing, but Deja vu feels more like a high def memories - like the very rare HD memories.

I wonder if Deja vu is not very simply a segment of real time processing that gets mistakenly tagged, 'from past' instead of 'happening now', or more likely gets tagged with both tags. It would explain why the memory feeling seems so real, because it is real, well what is happening is real, and feels so, but the memory tag is the bug in the software?

IDK, just a thought, and I like it better than any of the supernatural theories I've heard.

That is actually one of the mainstream theories of what deja vu is:

"Dual Processing (or Delayed Vision)
Another theory is based on the way our brain processes new information and how it stores long- and short-term memories. Robert Efron tested an idea at the Veterans Hospital in Boston in 1963 that stands as a valid theory today. He proposed that a delayed neurological response causes déjà vu. Because information enters the processing centers of the brain via more than one path, it is possible that occasionally that blending of information might not synchronize correctly.

Efron found that the temporal lobe of the brain's left hemisphere is responsible for sorting incoming information. He also found that the temporal lobe receives this incoming information twice with a slight (milliseconds-long) delay between transmissions -- once directly and once again after its detour through the right hemisphere of the brain. If that second transmission is delayed slightly longer, then the brain might put the wrong timestamp on that bit of information and register it as a previous memory because it had already been processed. That could explain the sudden sense of familiarity."

Basically he believes that because the information passes through twice, if it takes too long for the second pass to occur the brain has already received and processed the first pass through, so the second pass through seems like a memory. But since it occurred so recently, it also feels like it is happening now (because it is). Effectively similar to your idea that it is being "tagged as memory and real".

I'm sure you've posted this thread before?

Two ways to take that. At face value, I am sure I haven't posted a Deja vu thread, but I very well may have posted a random thoughts thread, tho I don't remember that. Or if you had said, I'm sure I've seen this thread before, I would have thought it was a deja vu thread reference. But now I am curious and will have to check, dam you Misono! :roll: :lol:

Okay please don't think I'm completely crazy...

I know it goes against the norm of many different religions... I believe in reincarnation. :shock:

While in heaven (or whatever you wish to call it), I believe that we plan out a path that we want our next life to take, so that we can accomplish the things that we came here to do (lessons, experiences, ext). That plan includes several "checkpoints," some people may have more than others.

Because we have free will, we can sometimes get off of our intended path. When you reach a checkpoint, and you're on the "right path," then your soul remembers it, and you get that deja vu feeling to tell you that you're on the right track basically.

I had a major deja vu experience at a time in my life where I felt like I was at a crossroad. I wasn't sure which way to go, and it was really stressing me out. I happened to be staying at a beach house in a state that I had never been to before. I walked out the door of the beach house, and all of the sudden that deja vu feeling hit me! Everything seemed like it had happened before (I'm I'm 120% certain that it hadn't), from the people that were sitting in the screened in porch, to what they were talking about, the exact things they said, to what I was holding in my hand, to walking out the next door. I could feel tingles in my body that I had to try to shake off because it freaked me out so much!!! I knew at that time though, that I had made the right choice.

Deja vu is one of the things I honestly cannot reconcile with my view of the universe... I'm a skeptic/atheist and the deja vu situations I've had make me wonder what is going on.

Usually what happens is that I will one day dream of a completely boring situation, forget about it when I wake up and weeks or months later, it happens exactly like that. For example, in one case back in my school days, I dreamt that I was in a desk in an unfamiliar room taking an exam, sitting down and looking at it with a feeling that something was wrong; then suddenly the principal's assistant comes in to say something and I react with a specific movement that I initially didn't understand what it was.

Move forward to a few weeks later... I was taking a maths exam in a room I never been in before (they used to mix the classes and move us to different rooms to reduce odds of cheating); the question I was trying to solve had taken me ages to come up with a solution (and it still didn't feel like the right answer) when suddenly the principal's assistant comes up to say that they were going to cancel that specific question as it had some key mistakes that couldn't be fixed by just changing some small parts. I then react - I move my hands in a gesture of disbelief for the 'wtf? I just spent so much time on this already' feeling. And that's when the Deja Vu feeling kicks in and my brain reminds me that I had dreamt of exactly that before...

And every single time I've had a feeling of deja vu, it has always been unique situations that had very distinct characteristics that haven't happened before or since then.. Which is why I don't think it can be a 'misclassified memory' as camstory suggested; the best theory I can come up with is that parallel universes do exist and can interact with each other (as some physicists have suggested), with some of those interactions leading to the Deja Vu situations.
