I think what surely will happen after we die is that our body will decay, our brain will also decay, all our informations, memory and knowledge will be lost.

This is what will happen in this particular universe.

But for full understanding of what might happen - it is necessary to know the basic properties of the universe - can universe repeat itself, is the universe oscillating?

I think that probability+chaos+little bit of metaphysics are very powerfull tools to explain this.

All in all, if the universe is oscillating - I think that "oscillations of our lifes" are also possible!
