Resolve

Sometimes I'm not sure of the earth beneath me. Usually I like this trait about myself, but lately it is hard to be at ease. I find myself thinking of my own, and my loved one's mortality. I'm dreadfully curious about the possibilities of a "next life" or "after life", but I'm also horribly scared of the death that comes along with it. Most are. Even if I had a near death experience, science has been learning that the brain simulates these sorts of images/sensations of heavenly environment while going through the process of shutting down, so even then I couldn't be sure. And I've been contemplating about the "spirits" as well. There have been a crap ton of experiments done trying to conclude whether spirits exists, or if we are just experiencing some natural phenomena. Personally, I think spirits are simply natural phenomena. Are "orbs" spirits, or electro-magnetic light reactions? Are EVPs the voices of the dead, or low frequencies that create hallucinatory sounds. Although, I do have to contest the second one. If it is a sound that has been recorded from a frequency lower than our accessible hearing, is it still a hallucination if it is recordable and audible as a humanoid voice saying something very specific?
