Every room in the Epilogue except the last one has one or more objects that you 
can stand behind. Open the red journal on that screen, and display its text. 
Stand behind one of the previously described objects. If done correctly, you 
will hear a sound and new text will appear. Note: If you open a green book, the 
red book will close, and the text will disappear. Time manipulation must then be 
used to see all four new text.

  First room: Read the red book, then find the hidden book with the scream.

  Second room: Drop down, read the red book, then use time manipulation to 
  rewind up to the left hand ledge. Walk behind the scenery until you hear the 
  sound again.

  Third room: Read the red book, then walk into the next room. Stand on the left 
  side of the green platform. Use time manipulation to rewind until you hear the 
  green book close. Walk back into the third room. Move behind the rock.

  Fourth room: Hit the switch so that the green platform goes up. Hit the switch 
  to bring it back down. Stand on the red book. Use time manipulation to rewind 
  so that the platform moves up with you on it. Run off the left of the 
  platform. Look behind the rock for the sound.
