I had the absolute worst nightmare of my life a few days ago, still makes me sick thinking about it... Any insight would be so helpful!!

I remember before the "nightmare" part I was walking down the road by my home and got lost down a side street... I think I might have been texting!? I heard sirens and realized I had left my baby girl at home alone (I can't even leave her with family members to babysit so I'm pretty sure the message isn't leaving her home alone! She is 1) I ran down the street trying to find my way back and saw smoke, my building was on fire. We live on the top floor and there was smoke and flames. I panicked realizing my baby was in there alone but they wouldn't let me in to save her... I looked up to our living room window and saw my great grandma (who passed away when I was young) holding my daughter. I finally had people willing to escort me into the building, when we got inside the woman with us opened the elevator and got inside, it instantly fell and we heard her scream, we all kept moving to the stairs (my feeling was, what an idiot for getting inside the elevator?! And just wanted to get to my daughter). The next thing I remember was hours later in my condo with people trying to help out, not sure if they were fire fighters or investigators, possibly a doctor who asked to see my daughter. She was on the couch with a paper towel over her, they took it off and under was a tiny plastic doll with her hair and part of her face burnt.... Then I woke up.

What a horrible dream... I heard once that when your subconscious really wants you to get a message it's sent in the form of a nightmare so you will remember upon waking... What could this possibly mean???
