 had that feeling where you're like repeating a day for like 50 years and you just cannot get to February 2nd. Just kidding. Hi guys, my name is Rebecca and today I'm gonna be talking to you about deja vu. Deja vu is French for literally already seen and so the definition for that is basically you have a really strong feeling that you've had this experience before or you've been at this place before but you haven't actually like you can't actually remember everything else about it. You just remember that you've been there before and nobody knows for sure what exactly causes this but there are a couple theories and one of the theories is the memory theory and so for the memory theory is sort of like your hippocampus sort of files short-term memory and long-term memory and puts everything in its place but sometimes when it messes up it might put a short-term memory in with a long-term memory to make you think like you've been somewhere a really long time ago but it could be this is the first time you've ever seen something this and so another theory is a dream theory and that is a theory that you actually sort of have dreams about stuff that's going to happen but you can't of course remember your dreams all the time so when something happens you feel like you've been through it before but you can't really remember when or how so that would be the dream theory and then the hologram theory is the theory that memories are all just sort of 3d holograms and when you have an object and it's clear that everything else is like really fuzzy so it'd be like seeing something like a book or something and having a really strong connection with it but can't remembering exactly everything else about why so those are the theories and some related sort of things to deja vu would be presque vu which was almost seen which is sort of the same thing as if you're trying to remember the name of that one country or that one celebrity if you're playing a game or something like that and you just can't think of it it's sort of in the back of your head but it's not all the way there and then there is deja on to do which is already heard which is when you're talking to somebody and you thought you already told them or you thought they already heard something that you said but they actually don't remember that at all so leave a comment down below of which theory do you think is most likely bye
