Is it normal that my only real fear is that life repeats?

DANG, this just blew my mind. Love thinking about stuff like this. Great, if your life is bliss. Interesting to think...

if this WERE true, is there ANY possible variable? is there any actual conscious decision? If I make a random choice is it really for no reason at all? If I make a random choice, will I make the same random choice in the next life (if it is truly random). Could there be any learning? Scarier even, could some thing change that would cause you not to exist at all,.. you'd be lost forever.. or for some vital aspect of your life or life in general or who knows what or who, to not be there?

Is consciousness itself some kind of a force? I'm afraid of nothingness. The most pleasant thought is the singularity being a unified, blissful state of consciousness. Ideally maybe even one that could remember all that had happened during expansion, but that might also cause distress. Not that I could comprehend such a state. But wow. Now I'll go watch some Carl Sagan...
