His explanation, on the basis of Jung's studies, about dreams makes sense. I too came to believe in soul and God because of the wonderful mechanism, called dream, within me which happens without my conscious mind being involved.
Interestingly, our actions are intertwined by conscious and sub-conscious mind activities, and it is like we learn driving--we consciously do it while learning driving then we switch to unconsciously driving later. Just like unconscious mind creates motion pictures called dream, it also created my body which is a micro universe--just like the Supreme Soul created the macro universe.
That means through the mechanism called dream, God has provided proof very intimately, in very personalized way, to every human being that there is proof for immortal soul and immortal Supreme Soul, if anyone wants proof.
