Dream of crowd, chased

There was a knock at the door. as i opened it i heard shouting had a feeling something not good was happening. a little girl whooshed in past me. i thought maybe she was being chased so i locked the door after her. but then i couldn't find her in the house. she kept disappearing. i would follow her but when i got there she was gone I could just see where she had been. there was something very strange about her. later i saw her in a crowd of people. she didn't want anyone else and was unhappy but when she saw me she calmed. i went to her and held her. she was happy and told me i was her mum.
