Techniques for lucid dreaming rely on this fact for you to be able to "detect" that you are in a dream. There is one where you need to look at time, look away and look again. The time will change or be in an impossible format if you're dreaming. Then if you're aware you're dreaming you can start to "control" the dream.
The funny thing is, I really do have an old alarm clock that does that. It's the most useless alarm clock ever, because not only can it not tell you the time, it can't even tell you if you're awake.
Saddest one was when I realized I was walking my dead dog. She was actually exhibiting behaviors I know she had been used to have, but not ones I had consciously remembered much when thinking about her after her death. I lingered on that one a bit. Still, dreams are dreams, and there was some weirdness, and I knew them for what they were. But that time, I did not fight the script.
> But that time, I did not fight the script.
That's a good way of putting it. In the past when I realized I was dreaming, I would take advantage of the situation and change things, give myself superpowers, etc. But in recent years my few lucid dreams have had really interesting plots, so I consciously chose to let things be and just see where they go.
I can relate. I saw my dead dog several times in my dream, and in the dream, it felt like she was never dead in the first place, not like I reunited with her, but it was just another of those regular days with her. So, even though I enjoyed the dream, I didn't have that euphoric joy of reuniting with her. I perceive everything as 100% absolute truth and only realize what's wrong after I wake up.
I did a bunch of lucid dreaming when I was younger (seems it was a lot easier then?), and even knowing things like that can end up making sense in the dream, you sometimes end up thinking "Well, it kind of makes sense the time went from 11:00 to 14:00 when I looked away, I did look away for quite a while".
For people who haven't lucid dreamed before, it might sound simple and almost stupid, but a lot harder when you're trying to look at your watch and everything makes sense but also not.
I wish I could figure out how to do that, anytime I'm dreaming all the weird inconsistencies and people morphing from one person to another and such all just seem to be normal.
What if there is no such module and whenever you believe you have experienced permanence it is because your brain confabulated it from what it actually observed?
I know it's a over-simplification, but maybe too much of it? 100% of your periphery isn't "generated" by your brain based only on what you've seen before, otherwise it wouldn't be possible to see stuff "at the corner of your eyes" or "looking while not looking" where you can see stuff without actually focusing straight on on the thing itself.
