A question for all those natural Lucid Dreamers out there:
In lucid dreams you have access to a larger area of your brain than when you are awake... you can see things you didn't even know you had stored away in the dusty corners of your brain... so in theory, wouldn't it be possible to view past lessons or lectures in school/university, and even revise subjects, in a Lucid Dream? I'm sure it would give you an unfair advantage 8)
