When I die, it's finito for me and who I am as an individual. I don't have a soul, if anything I'm just a personality that was formed as a result of neuron/brain activity, genetics and the environment I grew up in. There's a component of energy though that came from somewhere. I don't even know if energy is the word for it, it's just ...existence. I don't believe in a collective consciousness, but maybe there is a collective sort of energy/existence source. When I die, I'm gone, I don't exist anymore- but I could experience existence again, in one form or another whether I am another human or a cow or spider. I guess that sounds a lot like reincarnation minus the spirituality.
Ahh. I dunno.
