In this room, there is a fake window. This is a picture of a evening, it looks real.

Sit in front of the window, try to hear the sound from the outside of the window.

The fake window in front of you is so real that you think you already get out of this room and back home. You sit in front of that window and try to hear something. However, you know you cannot hear anything right now. You gradually have the feeling of you open your ear and your ear become bigger, but you know these are just the fake feeling. After you find you hear some sound in a trance, and you seems like you controlled by something to force you to sit in front of this window. Until the screen change to a sentence tell you that you finish, your mind back.
