What's causing my lights to pulse?

The lights in my house occasionally pulse--that is, they'll rapidly get noticeably dimmer and brighter numerous times within a matter of just a few seconds. I'd say "flicker," but they never seem to actually go completely dark. Does this indicate faulty wiring, or something else?

I live in an old (circa 1920s, possibly older) house in east Tennessee. The wiring coming up from the basement is, I believe, relatively recent vintage (1960s+). The overhead lights, though, are knob and tube wiring. They do the most pulsing, but even some floor lamps will do it. It doesn't seem tied to any major appliance's kicking into high gear (say, the air conditioner turning on or the dryer running). In fact, I've never been able to correlate it to anything, except one time where the lights in the bathroom pulsed in sync to the static I was hearing on my cordless phone. Any ideas? (I've tried googling for this several times but never came up with the right keywords to find relevant info.)
