Would you relive your life knowing about everything that'll happen and being unable to change anything about it?

Re-living a lifetime is exactly what we're doing anyway in this lifetime! This lifetime that we're all sharing now, was originally lived eons ago by us all and now we're reviewing it by re-living it again now.

That is why we have those 'Deja vu' moments from time to time... where those moments are showing us that we've been here before or that we've experienced these exact experiences before. Think about it!
