I will be honest in that I used to think these kind of pretend events were pathetic. Noisy. People not aware of their surroundings. An attempt at bringing life to the dead. I do not mean to be mean, just honest.
Now, I enjoy these event whole heartedly. Each person IS aware in their own way at their own level. The noise is inevitable but does not distract. The music did bring life to the dead and much more.
In the future, I will work at not judging before I am an integrated part of an experience.
