So, I have a plastic bin underneath my bed, and inside this bin is a Lego IR train controller. Now, the end of my bed is near the light switch, so the bin is almost directly under it. So here's the strange part. When I shocked myself on one of the light switch panel screws (accidentally the first time), the red light on the IR controller lit up, just as if I had pressed one of the buttons. I did it several more times, each with the same result. Any idea what could be causing this?
