changes what you pay attention to, and filters out stuff that's not immediately relevant. This is like our ears only transmit to us a small range of frequencies of all the sounds that are out there, the ones that are important to us. We don't need to hear what bats hear or what elephants hear.

And the visual spectrum, we just see a small amount of the light that's out there, just the visual spectrum that's relevant to the food we want to eat and so forth. We don't see the infrared or ultraviolet, which other animals do. So it's not surprising that the brain would also filter stuff out for us.

One is that when you have a near-death experience, you become very calm and very peaceful in this, and you stop wasting a lot of energy trying to escape from the situation, and that preserving energy may actually help you survive the event. Like a possum playing dead doesn't fight against things, it just sort of goes limp, and this predator loses interest and goes away.

It also may not evolve for the individual. but for other people in his genetic pool. For example, they see this person being very peaceful and saying peaceful things about death, and they become more calm about dying. So maybe for their benefit, not for the experiencers. There's various ways you can play around with what is the evolutionary value of this, but it's all speculation.

There's no way to prove any of this.

Right. And that leads to the question of how many consciousnesses are there? Is yours different from mine or are they actually part of the same thing? And, you know, many new death experiences use the analogy of a wave in the ocean. You know, it's made out of the same stuff the rest of the ocean is. But for a time period, it's got a separate form and location.

And then eventually it'll melt back into the ocean and become indistinguishable from it. They say that our consciousness is like that. For a time being, it seems to be distinct from the rest of the ocean, but it's not going to be that way forever.
