No, but I did mistakenly connect my driver seat belt to the center passenger buckle once and it took me 5 minutes and two stops to figure out what was going on. Got out twice looked around, checked doors. Felt stupid and relieved once I realized what was happening.
Sounds like you have a ground issue. I have a similarly weird thing that happens to my exhaust temp reading when I push on the brake pedal, but only when the lights are on. When I push on the brakes, the reading drops way down.
My guess is you possibly have a bad diode somewhere or a bad ground that's letting current backflow from one of your turn signals or the signal module through the module that controls that chime. You have to find the module first, then start tracing the wiring.
