wow that is a really weird dream. I used to have some EXTREMELY disturbing dreams.. and a friend of mine who moved to scotland sent me an "encylopedia of dreams" type book, and whether it is right or not, I figured I'd share with you what the book had to say.
(please excuse the typos) !
====================
BLOOD: Human blood in a dream is a symbol of success in one's endevors. Any dream in which you see blood suggests that you should keep contacts with a new acquaintenance to a minimum.
ABORTION: If a woman has this dream, it means illness or some form of unhappiness is on the way.
MOTHER: Indicates you are having difficulties with your partner - although the state of things willnot last for long if you take the hint and sort out the problem rahter than leave it to resolve itself in a less satisfactory way - and that you are turning back to your family ties for security.
ORPHANS: The figure of an orphan in dreams reflects unhappiness and misfortunes. A child that has lost both parents indicates that you have serious worries about the future.
PUPPY: Most dreams involving dogs mean that we can expect agreeable events to occur as a result of a friend's actions.
WOMAN (i couldn't find 'mexican woman): Surprisingly enough, any woman in a dream - whether she is young or old, naked or richly clothed, beautiful or ugly - indicates insincerity, uncertainty, bitterness or resentment - unless she is in the company of a man.

that's pretty much all I could find on your dream.. which doesn't make much sense if you put it all together (at least not to me)
