Is there any buddhist explanation for deja vu? I'm not sure we will find that in the pali canon (per haps in Abidhamma?), but is there any thera/senior bikkhu that wrote about it? Is it related to past lifes or any special power of the mind?
The psychology of C. G. Jung who wrote a preface to Bardo Thodol (The Tibetan Buddhist Book of the Dead) may explain the deja vu experience as restimulation of experiences of the collective unconscious in the bardo interval between death and the next rebirth, that he called "archetypes" or universal prototypes for ideas. However before drawing such a conclusion, know that the Sabbasava Sutta (Majjhima Nikaya 2) warns against questions which are seen as "unwise reflection" and lead to attachment to views relating to a self. They include: Did I exist in the past? Did I not exist in the past? What was I in the past? How was I in the past?
