Not paranormal, but unexplained: When I was a kid I was very sick with some kind of very severe immune reaction. While trying to figure out what was wrong with me, the doctors discovered that I have tachycardia. After the immune reaction went down and things became less critical, my mom took me to another hospital to get a followup EKG. This hospital had just gotten a new EKG machine (these were the types of machines that printed the results out on a very long strip of paper). When they hooked me up to it, the machine did not work. Not sure exactly how this manifested, but basically they could not get any measurements. They thought the new machine was just faulty, and to confirm they tried to use it on the child in line after me while we waited. It worked just fine on him, so they hooked me up again, and again it suddenly "broke". They checked me for metal or any other items that might interfere with the machine, and tried having a few other kids go before me as well, but the machine worked for all of them. I never did end up getting an EKG to get my heat checked, until years later as an adult.
