It is said that related souls travel together across lifetimes and they carry learnings from each lifetime. These learnings are not carried as logical packets in our brains, but as intrinsic prints in our souls as feelings. The deja-vu that we experience sometimes, is just our soul recollecting those feelings, behind the veil.
Even if it is tough, we ought to remember, 'time' is a human perceived concept. Outside of human perception, it is impossible to prove that 1762 came before 1962. The other thing to remember is that the concept of birth and death loses its importance as they become just events in the journey of a soul. As the soul journeys through lifetimes, the soul grows wiser.
