I suspect your terror comes from lack of familiarity with natural light outdoors, and is a product of always having the lights on plus not being out of a house often.

The night is not 'complete darkness', we can generally see fairly well.

Also, I suspect your presumption on assault risk and assault rates comes from media, which is designed around building fear. Fear sells.

So I agree that you find the natural world terrifying, I just wish you didn't. Because the natural world is what we are fit for.
