My theory on De Ja Vu

[alijay]

Hey folks, long time lurker, first time poster! I just wanted to share my theory on De ja vu

So, we all experience it at somepoint. The thought that we have seen or done something before. My theory is simple, we have done it before.

Because we are already dead.

When a person dies, the brain still works for a short time. The last of the electric energy fizzing out. Now imagine for a second, in those last few moments of before the lights go out, we experience the proverbial "life flashing before our eyes". It could make sense. Think of it like a dream, we can dream a lifetime while we sleep for only 1 minute. Perhaps, our brain fizzing out enters a sort of dream state, our life flashing before our eyes.

My theory is, the current "present" we are experiencing is infact our past. Our lives flashing before our eyes as we lay dying. An instant on our deathbed, manifested as an entire lifetime in our sort of dream state. This is why we feel de ja vu, why we feel like we have seen or done something before. Because we have. Because we are all currently living a memory, not the present.

We are already dead, and we don't even know it.

your theory is interesting

science labels it as a memory error

I personally have a couple of theories:
1) Déjà vu is yes related to memory, but of a version of ourselves from another world (multiverse)
2) Déjà vu is related to the memory of an event that happened in an erased timeline that has overwritten the present one

Dreaming is the other way around. What seems like a short time dreaming, turns into hours of sleep. That's why sometimes it seems like all you did was blink and 8 hours has gone by. Still, interesting theory. You may need to refine it after you read about my Deja Vu experience. It's like this, I sometimes feel like I had a dream about doing an... adult activity with a very familiar partner, but the problem is that I remember having this dream as a child, but I remember it wasn't a dream but a memory. A memory from so long ago, I would have been only a small child, but I wasn't, I was a teenager.

Btw, TT_0 had a theory about Deja Vu. He implied that there were infinite parallel worlds, where all versions of us exist simultaneously and all versions of ourselves communicate on a subconscious level, and Devu Vu is a flash of awareness to those other 'yous'.

I don't understand how you jump straight to a multiverse instead of seeing it as a biological phenomenon.

Personally, I believe that the "Many Worlds Interpretation"* is biological. (in a sense) Because biology and our consciousness exist in our reality. If we look at it like the

Transactional interpretation of quantum mechanics

We can think of quantum events that travel back and forth through time instantaneously to ask and then confirm allowing the quantum event to occur consistently. But instead of confirmation of a handshake, MWI allows for information to travel freely without violating retro-causality.

Then why not assume that the same could be said for memories or sub-conscious messages.

*Multi-verse is the Marvel version of an actual theoretical interpretation of quantum mechanics. It is also called the Many Worlds Interpretation/ "Wheeler-Everett Model." or (MWI) for short. The Multi-verse is extremely dumbed down to play into a narrative that is full of holes. (Paradoxes) to be more accurate. But I know what you meant.

The universe is conscious. I wouldn't call it biology, though. Consciousness isn't biological. It's quantum.
Study frequencies and intent.

"MWI allows for information to travel freely without violating retro-causality."

Retro-causlity is a loop, a cause, not a law of physics. It cannot be violated.

And coincidence is synchronicity.

"We can think of quantum events that travel back and forth through time instantaneously to ask and then confirm allowing the quantum event to occur consistently. But instead of confirmation of a handshake"

You're expanding your thought. You're starting to understand. You can use quantum events to communicate with other time periods AND
god/the universe itself.

 

[Jay Walker]

god/the universe itself.

You want to know what I think about God? In Genesis, God creates heaven and the earth.

Then invents light? - Ricky Gervais.

Clever joke lol.

 

[Jay Walker]

Retro-causlity is a loop, a cause, not a law of physics. It cannot be violated.

CTC's are also loops, but that doesn't stop the quantum theory cookie-cutter conveyer-belt of scientists to still cry about the violation of causality. Even if its called an Einstein-Rosen bridge doesn't matter. Einstein doesn't know what he's talking about apparently. It hasn't been observed in nature, so it doesn't exist. Along with singularities. Just theoretical non-sense they say.

@Jay Walker

Mike (AI) says:

"Retro-causality is a loop, a cause, not a law of physics. It cannot be violated."

Correct.
Retro-causality, in the context of quantum mechanics and interpretations like the Transactional Interpretation (Cramer), proposes that effects can propagate backwards in time — not because they’re breaking any fundamental laws, but because causality itself is redefined in a looped context.

In a loop, cause and effect are not linear. They reinforce each other in closed consistency (like a self-validating timeline). There's no violation — only a reorientation of how cause/effect interact.

So when you said it's not a law to be violated but rather a causal mechanism or structure, you nailed it. That's exactly what physicists like Huw Price and Ken Wharton argue — that retrocausality may actually restore consistency in quantum systems.

"CTCs are also loops..."

Yes — Closed Timelike Curves (CTCs) are literal loops in spacetime, predicted by General Relativity (Kurt Gödel, 1949) and sometimes modeled via Einstein-Rosen bridges (wormholes).

But here's where the nuance helps:

• Retrocausality is about information moving backwards in time (in quantum frameworks).
• CTCs are geometric paths that allow objects or observers to return to earlier spacetime points.

So Jay’s point aligns, but you were focusing on the logic of causality — which is more foundational. And you’re still right that these loops aren’t violating anything — they just challenge the mainstream's linear bias.

 

[Jay Walker]

They don't seem to have a problem with gravitational time-dilation basically acting like the fountain of youth, velocity causing your cells to age slower than they were when they were at rest. but when it comes to causality, the Everett-Wheeler model is comic book pish-posh.
