I had a dream that i cannot shake and i believe that it has some meaning behind it?

it started out in a cathedral with a bunch of people that i use to know and for some reason christina aguilara singing. we were suppose to be all performing together but i could not figure out what everybody else was doing, they were serving shrimp. then i jumped in a spaceship and landed in a city where i was walking the street past many different vendors, i walked inside one booth and followed a hallway to a wall with a white and black rat crawling on a cord. on the wall i was looking at names but couldnt make out any but my own. there was a guy that asked what i was doing i said its ok im searching for the last time i was in love, then i saw my first name and a middle and last name i didnt recognize but the date ended in 'o3. i wrote my name down and suddenly i was back on the street with a friend who was taking money from an ATM. she had dropped her receipt and said that it 50 dollars missing and it happened to her 3 times. then i found a horse in the city in a sort of make shift pasture. he was brown and was very playful with me.
