I’ve heard about this before and it used to happen to me when I was a lot younger. The only somewhat scientific explanation is that it’s a possibility that – somehow – the electrical currents in your brain interfere with those of street lights. Not just street lights, but other appliances too, like lamps, phones, credit card machines, etc. Because the lights and our own brains generate electricity it doesn’t seem like too much of a crazy idea.
The theory is that, usually, people who are under a lot of stress and who already possibly have stronger “currents”, are able to effect the lights.
