Your brain continually processes new information, and has access to existing information stored in it. That's consciousness. When you aren't processing normally such as sleep, that's not full or proper consciousness. When you're dead, you're not processing, you're not conscious, and your memories are literally rotting away.
A perception of something is your brain comparing the thing you're seeing against existing encoded information.
If you're nearly dead and your brain is running low on oxygen or is even damaged, you're prone to hallucinate.
Many people are prone to hallucinate things
every single night, and it's considered to be normal! So there are some very obvious reasons as to why science doesn't attribute much significance to a malfunctioning brain's imaginings. Back to a computer: I'll run a Tesla Coil next to my PC. Should I assign some kind of incredible significance to its BSODs, caused by data that shouldn't exist?
So maybe we don't have the nitty-gritty technical details of
why the brain does the specific things it does.
As we've seen in
the recent big bang thread, we've got some reasonable ideas of what the Universe was doing in its first tiny fraction of a picosecond of existence. Out of 13.8 billion years of existing, I think that covers most of it. Compressing the Universe down to a point where our ideas of physics are entirely broken
does present some challenges, but that doesn't automatically invalidate the whole lot of our ideas about how the Universe works.
It all feels like making a bigger deal out of something than it really is.
Sorry, but there'll come a day when your bio computer isn't going to compute anymore. Again, we apologize for the inconvenience, and welcome to the Universe.
