I pretty much reached this same conclusion :S
I'm constantly tormented how I'm not conscious about 7 billion people's mind but I am of mine. Why it happened till now? Can it be happening infinitely? Like if you play a video, then you pause it for billions of years, then play it again. If we were able to watch the video cutting the part where it was paused, it would look like it was never paused in the first place.
Maybe life is like that. I'll die, in a couple of billions of years, or other universes what I perceive as my consciousness will wake up (independently of the body form).
If I was told to close my eyes, and I'll get some drugs to fall asleep, then during that time someone is going to make a 100% exact copy of myself, where would my current consciousness wake up? In which bed, if me and my copy are in the same room?
How someone could convince my copy, he is not the original one? (if, for example, there is no video of the procedure). Would that prove there is no real consciousness as we perceive it and we are merely a byproduct of the laws of the universe?
Why did I become conscious in the first place? What if my homosapien body had never born?
Can it be that there is just one single consciousness but every creature experiences it on their own way? (like an OS being installed in different hardware. After some time they would look different, just like we all have different personalities and experiences, etc).
There is an hypothesis that says there is just one single electron in the universe, but all the matter is a kind of representation of it in time. That would explain why a positron and electron would annihilate each other.
I'm not an expert whatsoever on physics. I'm just curious of my own existence :)
