I've sord of come up with a theory as to what happens when you die. Your body has real energy powering it. Synapses in the brain fire off electricity. I think it's energy suspended in brain matter that we call ourselves (our consciousness). I think when we die it's just another form of consciousness that's completely different than anything we can imagine atm(energy suspended in something else, in space?). All the proof is there that it is not just lights out and nothing.
reminds me of the quote
"I have no doubt that in reality the future will be vastly more surprising than anything I can imagine. Now my own suspicion is that the Universe is not only queerer than we suppose, but queerer than we can suppose."
by J.B.S. Haldane
