The lingering moment before you die, your body releases DMT (Dimethyltryptamine) the same drug that makes you dream. The same drug found in all living animals . It's not an evolutionary trick to make you survive . Your body is choosing to release this drug now because it believes your fate, is too grim for you to comprehend.
So you dream. You dream that everything will be fine. You dreamed that nothing happened at all. It's in this moment that your body sits across from you. It tells you "Looks like we're not gonna make it this time" It shares a cigarette with you as you recollects the past before soon parting ways back to the atomic ether. Your body does this because it loves you. You never met anybody like your body. Your body has been with you everyday, good and bad. It even keeps a journal of your life carved in scars. Your eyelashes always wiped the tears from your eyes. But now its all ends.
Beauty of self preservation-even when dying.
