Makes me think about the "ASMR" effect and how some videos center around intentional stuff or just alternative medicine. It's like you know these crystals aren't doing jack but it's still relaxing on some level.
Same with aromatherapy. I know it's crap, my partner knows it's crap, but hell if I don't sleep like a baby if she sprays our pillows with a Lavender scent before going to bed; I sometimes take a bottle with me when I travel, and it knocks me out better than any amount of melatonin or sleep medication could achieve. I'm sure it's just association by now, but it works.
Well crystals are used for the pizeoelectric effect and involved in a lot of modern technology in relation to the EMF spectrum. So, there's at least "ammo for justification" even if that's all it takes for placebo's to be activated (Shepherd: I don't care what you believe in, just believe in something!)
