So I had this dream last night that I had somehow thought it be a good idea to sign up for the US Marines (seems ol' Blighty's army wasn't good enough for me) however upon arrival at what seemed to be a tower block in somewhere like Rio or Buenos Aires where I was to stay whilst I did my training (?) I decided it wasn't for me. I was sharing a room with someone who I really didn't like, a Buck or Chuck who talked with a southern drawl and I was the only new guy in the building so was subjected to much abuse.
Anyhoo, I thought 'sod this' wrote off a letter of resignation and refused to turn up for my first day on the job. In effect I'd gone AWOL. When all I really did was get drunk in my room (which took on the appearance of a rather nice hotel room). Feeling adventurous I went for a walk.
I was then chased through the streets of wherever I was by a female army general driving a coach, sent out to pick up all the waif and stray people who were trying to leave the army but were simply getting rounded back up and put back to work. I managed to make it down an alley, but somehow so did the coach. However, she had to stop the coach and help a western tourist who was totally out of it, with a hand made sign tied with string round his neck giving big bold directions to where he was staying in the city.
I kind of escaped, but wound up back at my room where Buck/Chuck was getting drunk. He said everyone went AWOL at some point during their day and to just chill out.
At that point, I woke up.
What the deuce?

I think that the dream might be your subconsciousness trying to disuade you from ever thinking about joining the US Marines.
My comment doesn't make any sense. Obviously, you haven't been thinking about joining the US Marines, otherwise you wouldn't have been so confused about the dream in the first place. I've just added to the confusion.
I shall retract my original comment and now say that I have no idea why you had such a dream. It's all very odd, isn't it?
