Dreaming of violence on a family bus

“Dream Momma, I’m a teenager living in Tampa. In my dream I'm sitting on a bus.  Sitting in the middle on the right handside. There's a two passengers sitting in front of me.  The very first is an elderly lady. A few rows behind me is a lady. On the left side behind me is a man. A man enters the bus (I think its my currently ex beau).  He's escaping some people who are after him.  Sits across from me (left side of bus).  He's relieved he got away.  I look at his head something had fallen on his head just before entering the bus...looks like several large flakes of dandruff.  He notices it too.  The dandruff is going into his head.  He exits the bus, realizing the people after him dropped this stuff on his head and its gonna kill him.  He takes a tonic thats on his right hip.  Drinks it.  But its too late he's gonna die.  He take the gun from his right hip.  Shoots himself through the mouth.  The bullet splatters through his skull, penetrating the bus window, killing the elderly lady.  At one moment, I'd moved over the the side he was sitting but moved back to my original seat, just in time to avoid the bullet hitting that seat, it then bounces to the rear hitting the male passenger in his hand.” (sic)

Dream Momma thinks there’s a lot going on in this dream so she doesn’t get crazy and blow it let’s look at it archetypically

First, this is a journey dream and all the passengers on the bus with you are the people in your world, apparently a violent world.
