Broken key dream?

i had a dream lastnight of a key hanging around my neck by a white string. there were two other keys, but the one key that broke opened my apartment. in my dream i live in an apartment building on the 7th floor. as i walked up the stairs the key somehow got caught in the stair railing and broke in half. i dont know what this means if anything. also in the same dream i was taken by a friend to the house i live in now. but this house had been remodeled with an addition. the friend began digging into the tile floor of the old house. he dug up a safe full of money! the safe actually had hydraulic lifts on to bring it to the surface .. it was amazing. then we walked outside and in a split second i was with my family and a few friends. in what seemed like an hour a lunar eclipse darkened everything. this was the most vivid part of my dream walking through new york city looking at the stars and also an eclipse. in my dream it was absolutely beautiful. any ideas or was it just a dream?
