What if time didn't move forward but instead we were just constantly remembering the future?

... my brain died while trying to understand this... tbf, its like 4am for me rn

What if we just saw our entire timeline and could just choose whatever moments we wanted to dwell in.

Well, time is a construct. We might be existing in the past, present and future at the same time but just not realize it. Physics still has a lot of mysteries

We would all be psychics.
