If the memory has a direct and exact relationship to an event or something in the past, Deja Vu has an indirect connection to it and is vailed, it refers to something but does not specify what it is and covers a wide range of possibilities.
If reminiscence is more memory-based, Deja vu is a disorder of remembrance, its central core is forgetfulness rather than memory, and this leads to more imaginative questions: Have I had a dream? Is it like a place I saw as a child or someone told me something about it and imagined it? Or was it a scene in a movie or video I saw somewhere? Deja Vu, on the other hand, emphasizes the role of imagination and instead of reaching a certain point in the past, it causes the imagination to continue in the link and has infinite possibility to continue and expand.
If the reference to memory is limiting and concluding, Deja Vu is the starting whistle.
In other words, this strangeness and timelessness is where you are, which makes you doubt whether you have seen it or not. It is being inside the "the new" that makes this incomplete reference: the shock of being in a space that is alien, along with barren recollection, stimulates the imagination, makes interpretation possible, and draws you somewhere between different or even contradictory things. This coincidence of the strange and the familiar, this haste and timeliness of the new space, as well as its mysterious acquaintances, is something we often think about.
