I still can't explain how my pen ended up in the fridge

I was sure I left my pen on the counter after writing a note. When I went back to get it, the pen was nowhere in sight. After searching the whole room, I opened the fridge for a snack and saw it sitting by the butter. I know I did not put it there because I was not even near the kitchen earlier. This kind of thing makes me wonder if small glitches are real. Have you ever had an object move on its own like that?
