Shattered glass in the kitchen

I was in the kitchen that is unfamiliar to me except for the dining table and the rectangular shape of the kitchen (which is from my old house).

I was washing dishes by hand at the sink and it is already late, around midnight. My mom and brother (both of them had passed away in reality) had both gone to bed. The doorbell rang and my mom and brother woke up to answer the door. It was the repairman who is coming to repair one of the ceiling lights that had blown out. They laid a plastic sheet on the entire floor area of the kitchen even though the blown out light was over a small area at the furthest end of the kitchen from the sink. All this time I was still washing dishes.

Suddenly my brother tilted something and it broke into many small shards of glass all over the entire length of the kitchen floor. I wanted to go clean it up but the repairman stood near the sink with a smile on his face and said not to worry, he will just roll up the plastic sheet and the kitchen floor will be clean again. So I did not need to any cleaning up.

Note: I had cut my finger on the glass from a shattered vase and it was bleeding in the daytime. So not sure whether this has anything to do with the dream.

Thanks for your help with interpretation.
