I had this conversation a few years back after telling someone about things that happen to me. Apparently it's not that uncommon, in fact, there is a name for people who experience this phenomenon. SLIders. (Its named that because a common occurrence is streetlights going off when such a person is near, so
Street
Light
Interference became SLIders.)
I can't tell you how many times I have been driving, and as I am passing streetlights they turn off, one after the other. Not the normal sulfur bulb relight. I can hear electronic equipment, and in times of extreme anger or stress, electronics sometimes malfuntion, only to work again normally later.
I don't think it is necessarily supernatural, but I think there is a connection between electricity created by the brain and waves and how it might affect other electronic devices. Kind of like how you aren't supposed to use a cell phone in a hospital because it might mess up the EKG down the hall.
Anyway, here are a couple of links regarding SLIders.
