What do you think happens when you die?

Now I'm no biologist or anything, I don't know much about brains but I believe after you die, the last remaining energy in your body maybe goes in your brains, and you see the people you loved the most in your last dream. After the energy is fully gone, there's nothing. It's just like if you were sleeping and didn't dream of anything. Just being unconscious in the void, feeling nothing and unable to think of anything, since our brain is the thing that allows us to think, It's only logical that after we die, brains die. if brains die we can't think.
