Why do I feel that this is not the first time that I am writing this book? Why do I feel I understand the phenomenon déjà-vu? Why do I have a feeling that we were the ones to build the noticeable pyramids and countless signs to remind ourselves of what is about to happen? Is the reincarnation theory just the way our minds remember living the same life over and over again? Why do you feel that this words seem familiar and that this is not the first time you are reading them? (Based on real dreams)
