A lot of supernatural stuff is just odd brain activity. Distorted human forms are a sure sign of hallucination in my opinion. These are just neural circuits firing off inappropriately. It often happens in times of lower sensory input, like at night, and the brain sort of loses grip on reality. In fact, I've learned to recognize when this is likely to happen and I accept that it will. Shadowy figures are a perfectly OK thing to experience at 3AM on the way to the toilet when you're half-asleep, for instance. Nothing to worry about.

I also appreciate the brain's ability to distort time. With the influence of drugs, I've experienced a year in a second. I've been in states where my brain created multiday backstories for sounds such that the sound is integrated into a reality indistinguishable from this one. There's a lot of room for convincing and very weird things to go on in your brain.

However, I do have one belief which is essentially faith since there's no way to prove it. I think the universe is a super-Turing computer. It operates over an uncountable set. This implies that the part of the universe which can be represented by ideas is essentially infinitesimal, it has measure zero in the set over which the universe computes. Our interface with this universe is limited to a countable set since we use finite tools and finite consciousnesses to observe it.

I think the quantum world is pushed right up on this interface and information from the larger universe has a tendency to cause very strange behavior on the matter on our side of the interface. Usually it's just random. But I think it's possible that there are more complex interactions, perhaps feedback loops with other parts of our reality or much stranger stuff. This line of thinking has made me more open to actual unexplainable weirdness. Essentially, we could live in a universe so big that it's mathematically impossible to even have ideas about any measurable portion of it.

As for death, my view of the universe sort of makes it not important. I don't think I am a separate entity so death doesn't really happen to me. My consciousness and memories will disappear, but I don't think that stuff is a significant part of me anyway. Since I am a conscious being, I spend most of my time being pretty myopic and behaving like I am a separate and vulnerable entity. But deep down I think the universe is so much more than that and I think that the real me is all of it.
