Unexplained nose ring incident

Years ago my girlfriend (now my wife) had her nose pierced at a local tattoo parlour. She was told to leave the nose stud in until this was healed, once healed the stud can be replaced with a nose ring. Unfortunately while asleep that night, the nose stud came out in her sleep. As this stud was not supposed to be removed until healed, we searched the bed for the stud, moved the bed, cleaned the room, hoovered the floor and the stud was nowhere to be found.Next morning we visited the tattoo parlour and had a new stud/design replaced in her nose.

Fast forward a few months (partner now with a healed new nose ring) we woke up in the morning and guess what, the original stud was sitting on the arm of the couch next to the bed inches from my face.

Any ideas? Absolutely bonkers
