Shattered glass/window

[HopeForever]

I know sometimes things are not signs but I often get signs and today something unusual happened. First of all, it's minor but before going to work my smoke detector battery beeped constantly as the battery was dying.
Then later after supper I heard a very strange loud noise like something falling. I looked around to find the source and then saw my home patio door window was shattered in a million pieces, but it did not fall. It hasn't fallen but there are cracking noises. Luckily it's a double sided window and it's the outer one that's breaking...

I called a neighbor to check it out and he said he's never seen anything like this before...when I google any spiritual meaning of broken or shattered glass a lot of different ideas comes up i.e. Illusions or dreams are shattered, the ego is breaking down, someone is in crisis or at their breaking point, etc.
