Please interpret this dream for me.

In my dream: I was sleeping in the bed and heard someone knocking on the door, I awoke to see where the noise was coming from to find it was coming from my prayer room. My sister was on the other side of the door and said that she was locked in and couldn’t open the door. I asked her how was she locked in as the door locks from the inside and not the outside so it didn’t make sense how she could be locked in. I was also thinking to myself, why was she in there and didn’t tell/ask me. I instructed her to turn the knob lock to unlock the door. We both jiggled the handle to the door but it wouldn’t open. So I went to get the key to unlock the door from my side. As I opened the door she thanked me for opening it, but as I went up the stairs I saw that she had all 5 of her kids in the room with their toys everywhere and they were sitting on my plants and couch; and the youngest 2 year old had his toy bike and was rolling the wheels on my white fluffy carpet. I instantly became annoyed as no one is allowed in my prayer room without permission & especially not children to play. So I was asking her why are the kids in here? I couldn’t understand why she would allow them to be in there, and then allow them to “be on everything”. It just didn’t make sense to me. I then I awoke from the dream.
