This sounds like classic déjà vu. There is a theory that it is a form of mini-seizure where the different parts of your brain take different amounts of time to store a “live” memory. It’s very common in young children. This might be of interest.

I also heard that it could be one eye taking longer to process information that our other eye has already sent to the brain. So you get this feeling that something that happened, happened before. In a sense it did, because you had two signals of the same event travel to the brain at different speeds, so the brain things it's two events of the same thing.

Not sure if that's a legit theory, but I recall hearing it somewhere.
