The "Visions Of The Future" achievement is only unlockable after you've 
beaten
the last level of the game, and viewed the credits. Then you return to your 
room
and activate the "Eagle Vision" ability. Take a look at the floor, walls and
ceiling, some strange messages should appear. Some of the symbols appear to 
be
Japanese, but I'm not sure. There also appears to be some sort of repeating
pattern amongst the symbols.
