Chad is speaking of lost information as in that the subconscious mind processes information just the same as the conscious mind. The only difference is because you have no real control over what the subconscious envisions (unles you're HIGHLY skilled) the things you see being deduced are always in abstract and symbolisms. Here's some basic information about dream-interpretation that will show what I (and Chad) mean:
When you die in your dreams - your subconscious is telling you life-altering change is afoot. Something major is going to, or NEEDS to change.
When your body decomposes in your dreams (teeth fall out, hair fall out, etc.) - You're having self-esteem issues regarding your appearence.
It's all really pretty simple once you get to know what's what. So, that being said, when you dream your mind is sorting things out and going over problems you face, just not with your permission or control. A smart person always considers what they see in their dreams, especially if you have a tendency of having pre-cognitive ones. Like you see scenes in your dreams that you see a couple of months later, etc. It doesn't mean you're psychic, it means you're very perceptive. This information can definitely be very valuable to include in your thought process and decision-making on a daily basis. Dream recall can help get over mental blocks, nervousness, etc. And mastering understanding dreams leads to more peaceful sleep, because when you sleep your mind is at-ease. This means better transition to REM sleep, and more rest. More rest equates to better energy in your waking hours. You feel rested, and loads more confident.
Meditation was a process initially used for battling insomnia, so the two are definitely related.
