When I was younger my dad's form of punishment was locking me in a small room with the lights off. A lot of people might think its abusive, but I rather enjoyed it. There were times when our power used to go out and the landlord wouldnt fix it until the next day, so I would constantly be in the dark. After as while I got comfortable in the dark, and even today, while we own our own house and stuff, I still keep the light in my room dim. The only time the dark gave me chills is when my college roommates and I would get bored and decide to walk through graveyards without a flashlight. We were dumb, I know, but alot of cool stories came from our little escapades.
