Experiments with terror

Recently read an article on modern music manly electronic, that adopts a more ghostly or other worldly tone. I'll post the article here http://www.spookyisles.com/2012/05/music-experiments-with-terror/

My words would not do it justice, but! What if some if this music was played to a group of people about to enter on a all night haunted vigil, or a evening ghost walk?

Would it change their perception?

Would it change what they see or hear?

I'd love to try this! And record results as well as a control group for contrast. Have a listen and maybe try it for yourself..
