Thoughts about the Cosmos

It is a pretty widely accepted scientific fact that over time the universe constantly expands outwards but eventually it will come back inwards

then my thought happened about dejavu (a dream that appears the same as a real life situation later on)
well what happens if when the universe collapses and re-expands it expands the same exact way and that is why we have the ability to have dejavu

does this mean our existence is fixed? and really it is meaningless or is this giving us the chance to make different choices even though we're prone to repeat mistakes over and over again?
