Beginning to hate car dreams...

So theres a few different parts to the dream. One part I can't quite tell if it was before or after the nightmare... but I was apparently part of a LARP acting group who was putting on a Victorian-themed story with a group of people that were friends with my cousin Robin. o-O I can't remember much else besides wandering through a huge Victorian mansion.

The other part... Will was driving along a busy highway/freeway when suddenly I looked up and a blue car was barreling down the wrong side of  the road towards us, hitting other cars. I hurriedly yelled at Will to move over and the car rushed past us and slammed into the back of a schoolbus. Suddenly the schoolbus was driving alongside of our vehicle... backwards. I looked back at it and saw where the car had gone into the bus it had decapitated a guy that had been on there... And something told me I didn't want Will to see this... thinking he would panic and feeling protective. So I yelled at him to speed up to try and outrace the bus.

Suddenly Will was driving up the concrete side of an overpass. I screamed "What the fuck are you doing???" and he said something about "Taking a one way road" or "one car way". I called him an idiot and told him to stop and back up before we crashed. (The bus part of the dream long-gone) He did... reluctantly and complaining about it the whole time.

Somehow it turned to where I retorted that I was thinking maybe we should break up if he was going to keep doing stuff like this and kept up that attitude. He replied with a "FINE THEN."
Then we were at his house, my family was still coming over for a party of some sort (I can't help but think it was to celebrate our engagement. o-O) We hadn't told anyone that we were breaking up yet because we didn't want to cause problems between our parents... but Will kept criticising me about stuff like not doing the dishes or cooking for the family. I was like "Geez. I've only visited once before!! It would have been awkward!"
Later when we were in the back yard (...though it looked alot like my back yard) I was talking to his mother who asked me to go in and do something in the kitchen, which I did. Will walked through and basically gave me the cold shoulder.
We got in another argument later... then I woke up.
