My body is constantly making predictions about everything that is going to happen in my reality, making a mental map. Then, when I go through the shift and start perceiving the new world, it throws me off balance. That is when I experience déjà vu. It always feels as though I am experiencing something that I remember experiencing before, but in the memory, I was also having déjà vu. It is a recursive experience and I take it as proof that I have successfully changed my reality.
