I im in a car with a girl and she lives in the hosue across the street from me. She pulls into the driveway and gets out of the car, telling me she will be right back.  So I am waiting in in the car.  Next thing i notice is that its rolling down my street (but her how and my street are how i know them in real life).  I calmly get into the driveris street and press the brake and turn into the next side street (which is a dead end) and put on the parking break. I look around and i see a large group of people having a bbq on the circle of grass in the circle of the dead end (it was bigger in my dream than in real life) and I remember it was the 4th of July. Then this truck that looked like am ambulence, but had this poster across the side that said Happy Memorial Day.  I see a man get out and throw a sharp metal throwing star into another man, kill him.  I thought i was ok because he seemed like one of the professional killers in Grosse Point Blank, so he was going to carry away the body and leave.  But then he killed another man.  Then he threw it at me, and missed.  Then he started thowing it at the picnic.  Nobody took notice at the fact that people were getting killed. At this point i was getting a little worried, but i wasn't scared.  I then asked him what he wanted, and he said to kill everyone. Then he pulled out another flat, throwable sharp object to kill people but he started missing with both.  So I picked them up and tried to throw them at him, and missed.  We started throwing them at each other.  I think i won (i forget this part of the dream).  Then my friend found me and I told her and told her i should call the police.  So I take out my laptop and dial Campus Po (at welleslsey) and decide against dialing the emergency #.  Then i decide against and dialed my parents. But i realize i didnt' want to wake the parents (wasn't my street in my dream).  So we leave.
