Well, at least for me it is true.
And how much of that was recalling every bit of dialogue, every tiny detail, and NOT condensing bits down into their relative importance? Most people can recall the big things that happen. They get the general gist. But playing something in "hyperspeed" and then rewinding and thinking about it, there are going to be differences for the average person.
Now, when awake we don't even use the full potential of our brains. When awake our brain needs to take information from our eyes, ears, etcetera and process it so it makes sense. But when we are dreaming it doesn't need to take in any information, and it doesn't need to process much of it because it already knows what it is for. Just there we eliminated quite a bit things the brain needs to do, giving it more thinking power to work faster.
Because, you know, interpreting senses is sooo much more labor intensive than making them up on the fly. And brains apparently aren't subject to the maximum speed of chemical reactions when asleep. And apparently any part of the brain can substitute for any other part. Remind me why this isn't bullshit again, preferably with some scientific sources?
Those studies don't show that waking time is the same as dream time, they show that it CAN be the same. Our brains are capable of working at many many many times faster speeds than we do during the day. When asleep that true power is allowed.
Uh...right...back to the whole chemical reactions thing. To send a neural impulse, a nerve cell generates an action potential. That potential travels down the length of the axon, and propagates by absorbing sodium ions, then kicking out potassium ions to reset the membrane potential. It then pumps the sodium back outside the cell and reabsorbs the potassium. All of this takes a few milliseconds just to recharge any given spot on a membrane. During this time, no other nerve impulse will register. This isn't even including neurotransmitters and other fun things. In other words, your brain has a physical limit. Its perception of time can vary (read: time dilation), but it operates at a fixed maximum speed.
And no, sleeping does not significantly free up brain space to be put to other uses. Let's say you aren't moving much, so your brain doesn't need those cells. What happens to those cells? Nothing. They have a designated purpose. They can't just suddenly hop in and boost brain power. Not doing math problems isn't going to make your brain visualize scenery any faster.
When people say you only use 10% of your brain when you're awake (which is bullshit, by the way), they don't mean you're using 1/10th of your maximum conscious thinking power. At any given time, there are parts of your brain at rest. They aren't doing much because their designated functions aren't required at that time. So say your brain doesn't have to contend with visual reception and interpretation. Except it does, you just aren't aware of it. Even when sleeping, it devotes resources to all 5 senses. Otherwise, alarms wouldn't get you up. It isn't that your brain suddenly starts working when your alarm goes off...it always has processes monitoring your environment. Alright, so let's hypothetically assume the brain doesn't devote any processes to environmental awareness when sleeping, or else extremely minimal ones. So what? Those processes not being used, as I've demonstrated, don't jump in and start processing something entirely different. No part of your brain does that.
Q.E.D. you're wrong.
