There was an arbitrary thing I planned on sharing a few months ago on the topic of deja vu but I saved it in a notepad somewhere since it got too blocky, for one. I kinda wanted to see more about it, though. Wait, I think I did actually end up posting it. Can't remember.
Not too long after though someone posted something vaguely similar, with some of the same not so much words, but phrase (a particular one) in the same thread, so I didn't want to post mine anymore because it would probably have seemed like I was trying to refer to him/her and get his or her attention, when I pretty much wasn't.. But I was just trying to say I wasn't sure if I've experienced "deja vu", as I had always told people that claimed to have experienced it that I never have so I couldn't really know what they were being ecstatic about, necessarily.
But there was this kind of weird thing that seems related to deja vu that happens sometimes, it's probably easier for it to happen if you're stoned though. It should be noted that it's fairly common to mis-identify someone (usually when they're far away, speaking somewhat too soon/getting excited) or hearing someone say something but they actually said something else (probably mostly my fault for not paying attention or having somewhat less than average auditory perception, listening to music too loud for some reason/ 'you're stuck in my mind, all the time'

) while stoned, so it's probably easy to lump them all together in the category of just being inebriated. One possible reason is, while stoned, I (can't speak for everyone, I don't think) seem to overtly focus more inwardly.. So sometimes, of course, I'll begin to, unintentionally, concentrate on a word or idea that seems more or less arbitrary and then someone will express it and all it does is snap me out of it. The differences, if any, are that it always happens almost immediately and that it builds up toward that moment. It gets more and more intense until it finally just pops. It's too easy to see how it can be arbitrary, plus it's not even weird at this point, more like a normal thing that happens sometimes which can be explained by familiar processes like a lot of things maybe, but for some reason I don't think it's the same thing yet.
It also seems related to another idea, which is timing things... Essentially leaving your house at a particular time, but that time had to be heavily considered. Such as, should I eat lunch now or later? Say you have it now, that's an additional 30 or so minutes before you leave while randomness is occurring everywhere still. I mean, you can leave then and go about your day but if you left sans the lunch (thus 30 or so mins earlier) you would have come across slightly different information, probably. Not that it matters, of course.
The point is, you would come across things you wouldn't have otherwise and be confronted by a potential choice mediated by whether it is feasible or not since it only seemed partially random. I'd attempt to operate on an odd mix of the two, which again can be manmade and arbitrary, not like it probably matters. I don't know what deja vu is but people make it seem like it has to do with destiny or something until someone explains it to be the brain doing what it normally does.
