Excerpt from Hideo Kojima's blog: October 2nd

I lost my shoes in last night's dream. I exited a plane and realized: "I am barefoot! My shoes aren't here… I must have forgotten them!"

I spoke with someone who worked for the airline, but he didn't know a thing about my shoes. I couldn't even remember when I lost them. When did I take them off? Perhaps I never wore them to begin with.

As I panicked, I traveled from place to place looking for my shoes; yet, none of these locations shared a border or had any means of physical connection. I simply was there, then in another place, and then another.

...and then the exam started! I suddenly remembered! I had to take that exam!

Was it a trial exam? An entrance exam? I had no clue! And even though the exam had started, I kept looking for my shoes. I gave up on taking the exam, but not on looking for my shoes. Everything became unclear... why I lost my shoes... memory weakened.

And on that subject, why was I even on that plane? Where was I going?
