      Cool question! I don’t know about you but I hate getting deja vu I find it so scary! One explanation for deja vu is that there is a split-second delay in transferring information from one side of the brain to the other. One side of the brain would then get the information twice giving that feeling of deja vu. Although I don’t know will we ever fully understand deja vu 🙂

      I had no idea to be honest but your question made me look into it further to find the work of Akira O’Connor. It may be the brain’s way of checking for errors in our memories and this might trigger at a given time/place and give the sense of seeing it before!
