Interesting. Mine also, vary.
Yours remind me of one I had. There was something in my arm, looked like a small hang up, I tried to pull it out, many times without success. When I succeed, a camera., that loom like a mini TV with legs (Size of a box 15/10cm ), came out, from a 0.5cm hole, and start running. I could not grab it...lol...then I woke up...
Crazy shit...
