I have to tell you that the title was the hook to this thread!

Hehehe
I had that once.
Every time I touched the ex I would get a strange vibration. Funniest part was it only happened when we were in the waterbed.
I got freaked out about it and actually tore the waterbed apart. I found the heater pad connection was broken and the fluid inside had leaked out!
Besides being worried about the PCBs in the bed, I wondered what would have happened if the water had touched the open connection!
I told you that to tell you this. Our bodies are electric. When the electric conduction of the nervous system is messed up, strange things happen. This is one of those strange things.
Leave it to you to get the fun stuff!!!
