Yes. I can tell you every imaginable detail, not only what I see, but what I hear, touch, feel, the force of the gravity, every tactile texture, the exact position of my body, etc.
I tend to doubt that. Nobody has recall that good. Certainly you have the memory of thinking, "Boy, you know, this sure feels real." I have that reaction, too. That, coupled with a couple key simulated sensations, is more than enough to give the appearance of a highly-detailed world.
From the fact that you can't recall a dream as clear as what you did yesterday you conclude that its because the dream experience is not as "real".
No, from the fact that I don't have absolutely perfect recall of what I saw/felt in a dream, I conclude that it's impossible to determine whether I saw everything in perfect detail, or merely got the impression I did. I do think that the latter is more likely.
I won't say the "dream experience is not as real" -- like I said, it feels completely real to me, too. What I'm saying is that I don't think our brain actually simulates a complete stream of totally realistic sensory input, moment by moment. That's just too much work. I think it just manipulates mental symbols ("that light is bright" or "this gun I'm holding is highly reflective" or "that countertop is really cluttered"), and when you focus on one of those symbols, your brain fills in a few key details (e.g. "that countertop is really cluttered" becomes "there's some unopened mail and some groceries on that countertop").
So, its easier to think you just "imagined" all that perceptual clarity while you were dreaming.
Yes. I think you are left with the memory of believing you were experiencing perceptual clarity -- or, if you prefer, the dream triggered a mental symbol that you associate with perceptual clarity. I don't think you actually saw a completely realistic visual environment. Like I said in an earlier post, I don't even think your brain knows
how to create such a highly-detailed environment. The laws of optics aren't exactly simple.
But the argument doesnt work. Whats the difference of "thinking" you were with your family yesterday and actually recalling you were?
Well, it's quite a large difference to them.
Actually, I think you're making my point for me. You seem to be admitting that the experience is not distinguishable from the mere impression of having had the experience. That's exactly what I'm saying. And I'm saying that, since it's a much easier job for your brain to give you the impression of highly-detailed vision than to give you highly-detailed vision itself, that's the more likely explanation.
Hehe, dont tell me you think a device as simple as a computer equals the brain! The "realistic" reflection and refraction you can see in the water when you wash your hands... is in the world or IN YOUR BRAIN!?!
Of course, in your brain! and this should answer your question. It is the brain where the qualia of those things reside.
Yes and no. Again, you're making my point for me. Your brain does not actually know all the details of reflection and refraction. Rather, when you see a shimmering pool of water, that experience is associated with corresponding mental symbols ("oh, that water is reflective and rippled"). It is those symbols which are being activated in your dream, not a complete simulation of the surface of the water and the way light reacts to it.
Think about this, you never perceive "reality", you only perceive electrochemical reactions on your brain. "Reality" is a construct derived from those subjective reactions, and every detail you can think about "reality" occurs within your brain.
That's like saying that every detail of a television show originates within the TV set, and the signal the TV set translates into a picture is merely incidental. I don't agree. You're ignoring the huge amount of objective, real-world information flowing into your brain through the optic nerve. That information is (mostly) absent when you're dreaming.
