Dream About Family In Subway

I had a dream last night where me and my family were in the subway together. But then all of the sudden they just left and said they were gonna be right back. So I just sat there and waited. I saw an adult man look happy and tried to talk to me as he was looking at his cute baby. I noticed his baby and thought he looked cute. But I was still curious about why my sister and mom had left me, I continued waiting for a few minutes until they came back. They were both very mad at me and especially my sister. She grabbed my cheeks and squeezed them really hard, I said “OWW YOUR HURTING ME IM IN PAIN!” Then she said “I can slap you in the face right now…” Then I was like “WHAT!?!? WHY!!!???? What did I do!?!?” My mom was there as well but said “You should already know what you did.. I’m not telling you..” I was so confused I was like “I have no idea what your talking about what did I possibly do wrong!?!?”
