This is something that happened to me when I was in highschool. I had to give a lecture, can't remember on what topic, but halfway the lecture I found myself as what I can only describe as a 'ball of consciousness' in the back of my head. My 'Ball Self' heard nothing of the world outside but only heard my 'Talking Self' giving a lecture. It was as if my Ball Self was looking through two tunnels which lead outside to my eyes from which I could view the classroom, whilst at the same time I could move about as this ball in my head and observe myself speaking and take a look at my own face from the side. I remember freaking out because I thought my Talking Self would 'stall', I couldn't comprehend how there were seemingly two 'me's' operating independently, so I guess I sort of forced my Ball Self to 'merge' again with my Talking Self.

Does anyone have any similar experiences?
