Deja vu is on our occult list. The benchmark for occultism is an altered state of consciousness. To have an experience or a remembrance of I have been here before, when you haven’t, constitutes an altered state of consciousness, wouldn’t you agree?
What cinched it for me was when I met someone who said that everyone in her family had these experiences; so it was generational. Also I used to have these experiences, but since becoming saved and delivered, they don’t happen anymore.
