So you go to a large art installation called the Mattress Factory. And on the second floor, the lights are dim. Extremely dim, so you can barely make out where the wall is and where is the entrance.
You enter a dark corridor. Pitch dark. 100% blind dark. You look back, but the door with the faint lights seems to have disappeared. You put your hands in the front, and find a railing. Turns out you are in a narrow corridor. You walk forward, holding on to the railing with one hand, and feeling for objects in the front with the other. And then the railing ends. And you find yourself in an enclosed balcony-like area, dark, empty, and you can hear your own echo.
And you can see what the artist wants you to see.
Would you switch on your phone light to see what the artist didn't want you to see ?
Its not worth it.
