The Idea of Death

Why is everyone always hung up on the idea of death being so hard? Death is probably one of the easiest things that could possibly happen. I don't understand why so many people fear it. The idea should be embraced. Think of it as a dream. A simple alteration of reality. It makes sense. I don't understand why people are scared to die. It's understandable to fear the loss of someone else but not oneself. Death is a release of any kind of pain. You could be scared of the pain of getting shot, the pain of an illness, the pain of loss, the pain of burning flesh.. but once death comes all pain is gone. It's a relief. Death comes and your time us up. Don't be selfish if it's your time. Welcome death with open arms. Accept it as one accepts a dream while dreaming. Life isn't really reality anyway.. is it? If dreams weren't the real truth then why would everybody follow them?
