Absolute darkness, even though your eyes are wide open. You assume that your eyes will soon become accustomed to the darkness, but this is not the case. You only venture through everyday situations with a cane in your hand and have to rely on your hearing and feeling. When talking in the dark, you literally can't see your hand in front of your eyes. A great recommendation! You see the world with different eyes afterwards. We didn't go to the dinner in the dark, but I hear it's great too.
