Dream analogy: Kristin is Legend

So I dreamt last night that I was with all my family hiding in this house and I had a rifle and a shotgun to protect us from werewolves.  One werewolf showed up and I shot him.  But then I couldn't find my guns cause my dad didn't think they were safe where I left them so I spent most of the dream in a panic that a werewolf would show up and I wouldn't be able to shoot it.  Finally, I found them again.  Then the dream shifted to us being out somewhere and there was this taco bar (like a salad bar) that had $3 tacos but my dad refused to pay for it saying that it cost too much so I had to go hungry cause I didn't have the $3.  WTH?  I think 3 things contributed to this nightmare:  1.  Yesterday on my nephew Ross' Facebook page I saw I am Legend is one of his favorite movies...well, my nightmare werewolves were the same ones from the movie.  2.  my good friend's mom died last week and the news has made me terribly homesick...I think the panic of not knowing where my guns were stems from the fear of me not being there when something bad happens to my family.  3.  I'm really struggling to live on what I make here and am constantly evaluating how much money I have and what I can spend and if I can eat out or not.  I feel exhausted today...for some reason, I don't think I got a good night's rest!
