monday night i suffered from insomnia for the first time in over a year. this didn't make me happy in the least, but is really not much of an interesting point. it does, however, mean that i was tired yesterday, and when i am tired, my brain works slightly differently than when i am rested.
case in point, although not the first time that i noticed it, i found an interesting slice of time yesterday. if you have a nightlight that automatically turns on and off in a room that you commonly turn the overhead light on, the bathroom for example, you may have found yourself passing through the moment that i am about to describe.
there is a time between when you turn off the overhead light and when the nightlight comes on. visually, it is a strange transition. the bright light goes away instantly but the little nightlight takes a moment to get going. this leaves you in the dark for just an instant and to me is a strange visual transition. probably not all that interesting to most people, but i have always liked the way that it worked.
