Speaking of dreams

I woke this morning almost in tears, after a terrrible nightmare had rocked my sleep, yet again. It's pretty typical for me to have them, but they never get any easier to deal with. Each one a little worse than the last. This one was about one of my close friends. Not fun.
I was driving along on in a car I haven't owned in more than 5 years, on a road that weaved through the marine corps base. The base, however, was not the one on which I live now. PMO pulled me over for what I assumed was another speeding ticket. I was crying so hard because I knew I wasn't speeding, but they wouldn't hear it. They made me get out of my car, told me to find another way home as I was not getting that car back again. I somehow managed to see the police report and saw that they were picking me up on suspicion of drugs, and apparently a headlight out. When I arrived home, to a house that I do not live in, and have never seen in my life, my friend was standing at the top of the stairs waiting for me. For whatever reason, she had moved in with my family and me.
After relaying my story to my friend and realizing that she did not seem at al surprised, I asked her if everything was okay. She replied with an evil laugh and the confession that she had set it up, and that PMO would be coming to take me away soon. She said that she was jealous of what I had accomplished in life, and of all the nice things that I had, so she was taking it. Apparently she had only asked to move in because she liked my daughters bedroom and knew she could have her kicked out of it for her. In disbelief I went to walk up the stairs towards her and she hit me with a metal bat.
That woke me up. I was almost in tears and messaged her immediately. Everything is as it should be.
Generally, I can make a decent connection from my subconscious to my dreams, but this one has me stumped.
