In this room, you get a recordplayer with a short music and a short dancing video on the screen. It's not a difficult thing to learn to dance follow the music. However, have you try to dance without music and just look at the no sound video?

Try to follow the video and the music, and dance correctly with the music.

You look at the dancing video for a wile and you said this is really a hard dancing challenge. You are not very bad at dancing, but music is a very important thing for you to learn how to dance. You feel stress, but you still force yourself to dance follow the video. The first time you try it is really bad that you cannot follow any movement. After you tried 5 times, you stopped and sit there. "Why I choose this challenge?" You think this is the hardest challenge in the whole 6th Sense.

5min later, you stand up and keep learn the dance. After at least 25 times study, you finally remember the dance and could follow the music by looking at the video.
