Is that you, Luminon?

I think that's possible to a certain extent. Our brains can be quite good at deceiving our perceptions of reality, and I've heard of stories where people felt like they spent years in alternate realities after taking strong hallucinogens. I'm hesitant to support the idea of a "never ending" dream though, for obvious reasons.

Huh? 

It should feel the same as on Earth, unless you mean that it was actually exposed to outer space. If that happened, it wouldn't be "awkward;" you would die almost instantly. 

To dream requires changing brain states. To change requires time. Although someone with inactive time-keeping neurons may not be able to *keep track of* time, time still passes inexorably. Without time, there is no change. Without change, there is no dream. Our *perception* of time is not the key. The key is that time is independent of our perceptions of it.

When you die, you might experience a dream-like state of perceived timelessness during the short time that your brain is still alive and infused with DMT. However, that state of 'timelessness' is not outside of time. It begins and ends. It begins with the DMT and ends with brain death. After brain death, the dream does not continue.

DMT may change your perception of time, but it does not change time itself. Consider that a DMT high ends when the drug is metabolized out of your system. When you look at your watch, time has clearly passed during this high. It is only the perception that was changed.

When you die, your brain dies. When your brain dies, there is no longer perception.

So, no, there is no afterlife. After life is death. That's kind of the definition of death, 'after life'.

The closest idea I've heard that makes any sense of a 'life' after death is the idea that the ideas and legacies and memories we leave behind with other people will remain in the world long after our biological bodies, and brains, die. But this is not what most people think of when they talk about 'life' after death.

The second best (only because it doesn't yet exist. When it exists, it will be the best) idea I've heard is that one day we may be able to scan our brains and create conscious machine-intelligences based on our original biological minds. This machine-mind would be a 'mental clone' of you, with all of your memories, beliefs, emotions, personality, etc. It would just be in an artificial body, rather than your original biological one. Being a 'software' mind, it could theoretically be transferred from one body to the next, essentially achieving practical immortality.

But it will always require a functioning body. Software doesn't function without hardware.

Yes, but the point was that your brain can trick you into thinking that it's a lot longer than it actually is.  

Well yeah, if you look at it that way, but the original poster said never endijng, so that's what I was reffering to.

First, I'm not sure if that is actually true. I have heard that claim before, but I have not heard of any actual brain science that supports that claim with evidence. It could simply be one of those random claims made by people who take drug experiences too seriously, like, "Whoah! This must be what it's like to almost die! Cool, dude. I bet the brain releases a whole shitload of DMT just before you die! That would give you an infinite dream. Whoah! I think I just figured out what the afterlife is!"

So, you might want to investigate that claim to see if it's actually true.

Second, even if it is true, it is not terribly surprising. Assuming that the brain uses DMT naturally as a brain chemical, then obviously there must be a store of DMT in the cell vacuoles of the neurons, as this is how such chemicals and neurotransmitters are stored for usage. A vacuole is like a little bubble or packet inside the cell which stores a chemical or some food for the cell.

When the brain is in the process of dying, it desperately tries all sorts of things to stay alive. It is not surprising to imagine that in its last throes of desperation, it starts to randomly release its stores of neurotransmitters and other brain chemicals. Kind of like, "Well, me Matey, if we're going to die, we might as well go out fighting. Ramming speed! Fire all cannons!"

Even if this is not the reason, there is a final reason which still makes it unsurprising. The brain is dying. When cells die, they self-destruct. There are special organelles called lysosomes which contain highly destructive enzymes, usually used for digestion of food. A cell which triggers its self-destruct mechanism, which is called apoptosis, ruptures its lysosomes, which releases the enzymes, and the enzymes proceed to destroy the cell from the inside out. Such destroyed cells basically release all their contents into the surrounding intercellular space. If DMT is such a powerful chemical that it only takes a little bit to cause a high, which I seem to recall is the case, then it would only take a small proportion of cell deaths to trigger a 'massive' (relatively speaking) DMT infusion.

So, either a) it's a myth, b) the brain is freaking out and desperate, or c) the brain is actually in the process of self-destructing and consequently releasing its stores of DMT.

If you want to postulate "shit happens", there is no need to conflate "shit happens" to anything more than "shit happens".
