Re:
Yeah...I had a similar "self-induced, dark experience" recently. It was early afternoon (4:00ish) and this killer storm rolled in as I was stretching. You know the kind, freaky, multi-colored clouds, boomin' thunder and massive lightning strikes close to the ground and it became very dark. I work-out at home and it was a leg day so figured I would try something different. I turned off all the lights (still enough natural lite to see OK), cranked-up some (old) Ronnie Montrose and started poundin' out the squats. It was pretty cool with the thunder crashing, shit vibrating in the house and wicked lightning strikes flashing off the walls. I'll do it again some time. Pretty cool mental & physical rush.
