I was sitting in my bed using my computer. It was almost out of battery, so I got up and grabbed the charger to connect to the outlet. Then a strange thing happened: when my hand got near the outlet, a small lightning/spark came out of the outlet to my finger, and it shocked me. For my surprise, the shock was incredibly mild, similar to a static shock. Why did that happen?
I know that it is almost impossible for anyone to understand exactly why it happened with only this description, but I'm only looking for ideas of why that might have happened. Here are more details to help out: - The distance from the outlet to my finger when the shock happened was about 1 inch (thus, the lightning had a similar size). - It is a dry and very cold day (7 Fº, although I'm indoors). - I was using sweatpants. When I got to get the charger, my butt slid across the bed (maybe the friction charged me and what happened had something to do with static or something?) - I usually experience lots of static shocks in the room I was in. It has a carpet and metal door knobs.
Why did the lightning happen? Why was the shock so weak? And the fact that I slid across the bed had something to do with it?
