 In the third dream sequence (Part 3, Chapter 6) there is an easel in  Maxs office. In the real world (Part 2, Prologue) it details the  plot points of his case, but in the dream it says, "Wake up! You are  in a computer game!" The "wake up" message can also be seen  fleetingly in an earlier dream (Part 3, Prologue), but you need to  see it quickly before the dream ends. It is also a reference to the  first game, where Max received the same message in a dream sequence.
