wouldn't I be bothered with lights and stuff if I had epilepsy? This seems to come randomly, but rather when I am relaxed, I think. And it's exactly the same "view from above" as when I do willing astral projection. The exact same. It all started after I started experiment with AP stuff.

I am not doubting your experience in a least. But mine is not deja vu like. It can be controlled the moment i realize it's happening. There are not black outs, I am pretty sure of that.
