Dream of boyfriend, daughter, died, injured, mad

My 20 year old son was backing up an SUV vehicle towards my parked vehicle (the parked vehicle was my vehicle I actually own). My son does not have a driver’s license in real life and I did not recognize the SUV he was driving. My boyfriend was standing beside me. My 5 year old daughter was standing at the back of my vehicle talking with my boyfriend and I. She could not see my son backing up towards her. However, I saw the vehicle come towards her and although I was thinking I should rescue her for some reason I was frozen and time went slowly as her body was squished flat between the two vehicles. My daughter died. I was crying and upset but appeared as though no one but me cared. I was afraid to look at her squished body and somehow my boyfriend told me not to worry that it was ok. I remember being angry at him for not carrying and I was crying (enough that it did wake me from my sleep). Then I remember that although she clearly was squished and died in my dream and I knew that she died I was carrying her, she was able to talk and she was not squished like I saw. What she had instead was large cracks and a bump on her head over her right eye but some how I still knew she was dead. I was calling out and crying and frustrated that I wasn’t getting help. I think my 10 year old son and my boyfriend ’s 11 year old daughter were in the background but they did not appear to really be paying attention. It was as though they were busy doing something (I do not know what). I do not remember anything more....but then my dream moved into an old townhouse. A kind of boyfriend of mine from grade 9 was sitting on a couch in this town house. There were others in the house but I did not know them or see them, I just knew they were there. He was dirty. He did not have a job and asked me why I didn't remember that from the last time we talked. Then I remembered he had an injured foot (which actually I seem to recall from an actual dream I had before). He showed me his foot and it appeared more healed but not completely healed from the last time I saw him. For some reason we were waiting for a high school friend of mine to come over to this town house. Some how I remember I was standing looking down from the top second floor to the doorway entrance of this townhouse to keep checking if she had arrived. It was almost as though I was peeking. I do not know why these two people where associated in my dream as they did not know each other and are from different periods of my life. For some reason I was worried she would be mad because there was a house full of people. I do not think we were in high school but that it was present day. I do not remember any more.
