can anyone explain?

i just had a thought-
what if we meet each other, for example, we both go past each other in the street, we had some physical contact, maybe just being next to each other in the street, but neither of us noticed each other, but we did meet. would that meeting actually have existed and if so thru who's perspective? where does that meeting exist? where was it seen? was it really seen ?if it happened, did it happen? where did we walk by each other at that time? in someone's head? in space? where did that happen?
or am i thinkin into that too much?
