If suddenly you find yourself traveling down a long tunnel towards a soothing, ethereal light and you see Grandma waving to you from a distant garden with harp music in the background, relax. You're not dead. When you die, you'll know it. Death isn't going to sleep. Death is waking up. It is actually like being startled awake. There is no afterlife. There is merely life. What comes after the biology is magic.
