Collective manifestation - listener question

If the outside world is only ever a reflection of our inner life, which it seems to be, how is it that things appear to be happening for everyone? I am speaking about vaccination schedules, governement restrictions, masks, lockdowns etc. Though we are all experiencing these things differently, they are happening..arent they? Just as in world war 2, there really was a war even though everyone had their own unique experience of it. Is this to do with collectively manisfesting something on the outside due to our similar inner worlds??
