Newbie....Woke up hysterical....any thoughts?

[shylah]

My dream starts with me driving in my car, at night, in a hurry to get somewhere. I drive past a school, there are a few people outside and a police car. I don't know if there was a dance or some type of function, disturbance, I don't know. I have my car window rolled all the way down and I see a police officer on my right. He says to me "I need your license plate number mam." I slow a little and point out the window towards my tag. My tag is my name. I think to myself, well he should be able to remember my name and keep on going. The police officer is a guy from my town who died a few years ago but was not a police officer. He was shot and killed. I did not know the guy personally but he was my age and I recognized him. He was the nephew of a friend of mine that I used to work with.
I keep driving down the road and then I get to an intersection in town and turn right. There are two lanes to drive in. The inside lane has some sort of construction going on. The road is in huge chunks, the stop lights aren't working, there are lines down but I still manuever around the pieces of road and stay in that lane. I take another right.
When I turn down the road my lights flash across a car with some people around it. I get out and there is not much light but I see legs underneath the vehicle. The legs of a child. There are two police officers, neither of them is the guy I saw earlier and two women standing there. I hear one of the police officers say "this is the third one we have found like this." It is a boy between the ages of 3-5. He is dead and somebody has placed him under this car. The officer hands the boy to one of the women and I see his face and he resembles my friend's son Ethan.
I am in my friend's house, Rachel, next and I don't recognize the house but I know it's hers. She is sitting with a baby girl on her lap who has lots of dark brown hair. The baby is just old enough to set up propped up against her but still has a wobbly head. Her son Ethan is standing on the bench she is sitting on kind of hugging up against her. I think her husband is sitting beside her but I am not sure because he is kind of fuzzy to me. There is a kid of a bout 5 kind of leaning against him. Her oldest son is not there that I see but I am not concerned in my dream. She looks at me and says "Is everything okay, is something wrong?" I said "No nothing is wrong, I thought there was but there is not."
I walk out the back door with a police officer and it is just known between us that the boy was not who I thought he was. He says "One of the other women thinks she might know who he is, he just really needs his mommy right now."
I woke up at 3 this morning hysterical over this dream. I dream things all the time about my family, some of which come true, and I have never woke up and been really upset. I woke my husband up and he of course told me "don't worry, it's just a dream." At first I thought something was going to happen to one of my kids but I have a son who is 9 and a daughter who is 2. Then I thought maybe it was about my friend. In October, it will be a year since we last spoke. She is married to a man that abuses drugs, her occasionally, and has left her many times and she has gotten fed up and left him many times too. I always supported her and did everything I could to help. The last time we spoke we got into a spat over the fact that he dictates what she can and can't do. I got fed up and we exchanged a few words over email but that's it. I found out last month that she is pregnant with twin girls they think, who are sharing a placenta and only have a 50/50 chance of survival. A mutual friend of ours told me otherwise I would not even know she was pregnant.
I am pulling certain things out of the dream about her...but why all the rest of the crazy dream? I would appreciate any help or ideas.
