Dream of person

I dreamt that I was looking after my brother, I think I was his full time Carer but he was much younger and I much older. We were sat in the kitchen when I saw someone walking up the hallway and opening the living room door they were wearing a mask. I went to confront the person, removed the mask and it was a young boy. I told him to sit tight while I got changed from my pyjamas and marched him back to his mums house. When I got there and told her she invited me in and cried and kept apologising and I felt there was nothing else to do but console her.
