Has anyone here on the forum studied Deja Vu?

[Juan]

Yesterday I had a Déjà Vu, but also in past years, to the point that I had to take a break cuz I got freeze or shocked for a couple of seconds trying to ingest what is going on. And this rise the question if anyone has studied the subject, maybe even asking while being on psychedelics, did we already experienced what we are living now? Sometimes on these deja vus it feels SO OBVIOUS that I already lived this moment or life (and depending the deja vu, I can sort of try to guess the age I had the dream in the past, usually years ago), but, idk how true is it.

I haven't researched it but thought about it. It seems it is caused mostly by past dreams and past similar experiences. However, there is that 1% of Deja Vu that has nothing to do with the past. It seems it brings you such sudden intense lucidity that you are almost able to predict the future.
