There's a guy who lives directly across the street from us on the second floor who has this pulsating blue light in his dark room, and it's on all the time. The room is always dark, and the light is always on. We didn't know it pulsated (pulsed?) until we stared at it for 10 minutes straight trying to figure out what it was. Then we noticed a slow, steady pulse. As far as we know, the room exists solely to make people wonder what the hell goes on in there.
It could be one of those lights on the CPU of a computer, but it's too bright. It could be the clock on his microwave oven, but it pulsates. It could be that the guy has an E.T. living in his apartment, only its heart glows blue instead of red and it stands incredibly still for four months at a time. We just don't know. But we see it when we go to bed and we see it when we wake up. We see it when we're going on our sixth straight hour of watching the second season DVD boxed set of Lost, and we feel its glow when we cook dinner and trim our fingernails.
But we're at peace with it. It means us no harm. It is a calm, soothing mystery. And maybe it wants to lull us into a false sense of security.
Here's a picture:
Any ideas, let me know.
