How about maybe I've had a lot of other experiences in our invisible world, and the picture I've built up from those experiences is that the personal ego dies when we die. Without the personal ego, a life force may (or may not) exist, but the person does not have eternal life or any other life.

All my knowledge is used to build up a coherent picture of what is, and that includes experiences that involve invisible realities. I'm very, very sure that there is not god, and there is no life after death. There are other things, but they do not fit any of the religious orthodoxies.

You said, "Do things that can operate outside the "laws" of nature trigger you by shaking your belief in an ordered universe?"

As stated, we do not have names for things outside our known universe, and we don't have instruments to measure them. Nor do people have the senses to identify any of it. We can certainly see according to a particular visual spectrum. After that we can't. Occasionally, some people can, but it is only a limited sight.

There is no 'supernatural.' There are things that are invisible to our eyes, our hearing, etc. That does not mean they are supernatural- just that our understanding of the world around us is limited.
