You have 3 arrows of time: one points from the smaller universe to bigger universe, second points from universe with lower entropy to higher entropy and third points from what we perceive as past and remember to the future that we don't remember. Right now those 3 arrows of time are aligned and points in the same direction. It's possible that first arrow will change direction at some point, second will not and we don't know about the third. So on universe's level it's complicated. On human level we simply remember events "behind on" on the timeline and don't remember the ones "in front of us". It's not clear why or if this can change. Maybe it's different for other organisms.
How does time work? 🤔
