Your character will sit down beside the bed, take the Dreamer’s hand, and whisper, "I am not the Taker tonight. I am the Gate. Sleep, child."
Warning: On your first playthrough, the game lies to you. It flashes a fake "Low Battery" warning at the 7-minute mark. Ignore it. That’s the Taker manipulating your UI.
To achieve high quality, you must fire the shutter exactly between after the first auditory cue (the “whisper snap”). Use a stopwatch. Yes, seriously.
