There currently exists a BIG topic for this kind of thing. The BIG PreCog Dreams Topic (Part 2)
You should check it out, there are some incredible stories in there. Some more exact in detail than others. Some even were exact to the most minute aspects. There are also a number of small topics about dreams that are psychic, precognitive, prophetic, what ever you want to call it. Have a look around 
Very interesting experience you had, though.
