I have experienced this feeling at least 5 times or more.
That is a short feeling triggered by certain arrangement of objects, which feels familiar. I have experienced a similar feeling after looking at a certain object for several times and returning to look again, but Dejavu comes on first look.
Maybe someone could share perspectives on what is Dejavu in theoretical sense ?
To me it seems to have different possibilities. Something that happens in a parallel life, something that happened really in a recent past and happens again , so perhaps like a milestone we have to pay attention to, and last, something that will happen in the ‘future’ but feels like Dejavu which makes sense too since in fact time is not really linear.
I don’t know about parallel life because my consciousness is too low, lol but I definitely had a memory of a recent past, and for something in the future, the Dejavu detail presents itself as something odd to which I need to pay attention, and this oddness each time makes me think… that it will become a Dejavu thing, that it will come back in the future. And it usually does and It makes me smile.
There’s de ja vu where one part of the mind/brain sees something in a split second before the other part of mind/brain sees it.
Also, there the de ja vu that’s more like a vision of something past or future. Maybe things what Flofrog means. If I have de ja vu and trade thoughts &/or emotions with the past or future, I call them time tripping.
