Miraculous Medal Rosary

what does it mean when a picture of the virgin mary falls down?

I believe in signs from a higher power, so this kind of freaked me out when it happened. Just a few moments ago a picture of the virgin mary, its actually a card in a frame my mother in law received called "the miraculous medal". It had a rosary hanging from it and it fell too. It just randomly fell, nothing else just those two items. If anyone can SERIOUSLY the symbolism of this, please let me know, I'm very freaked out by it.
Ok the nail was fine and there its a one story. No one was awake for it but me and my husband. There was just a loud bang and then they were on the ground. I just wanted to know if there was a symbolism to it, not smart ass answers. Thanks!
Oh and no open windows.

It means (imho)

Start praying the Rosary daily and invoking the Miraculous Medal, they are not just decorations but very real means to the peace you and your husband seek and this world cannot give.

you are right to perceive this as a sign. again imho

Peace
