Playing the guitar, writing a novel that will never get finished, living in my moms house (Not the basement), writing a rock opera that likely wont even get halfway done, learning a bit of Spanish, trying to lose 180 pounds, trying to learn Tai Chi, and trying to resolve past issues. That really depends on religious belief I'd think. If you believe you have a soul, but there is no heaven, then you would probably be conscious of the absolute nothingness. And if you are talking about the act of dying itself, I would assume its like doing a large amount of drugs at once, as your body goes so do the higher functions, the brains chemical inhibitors would probably cease, so your brain would be flooded with dopamine and serotonin, and surely your veins would be pumping with adrenaline. And if the human pineal gland really does secrete DMT while we sleep, you could probably be pretty sure that would be in the mix.
