Whats the best dream you ever had (keep it clean

) and the worst one? I think it would be kinda cool to hear about what other people dream about.
My best one was just before i went to New York a few years ago, i had a dream which seemed VERY real and involved a city with lots off walkways above the actual city below, the walkways were above scattered clouds, but the city itself was below them so there was a really stunning view. I would look down onto the city below seeing everything that was going on and above planes were flying over my head and banking left and right with the vapor trails behind them making cool patterns, there were people everywhere doing weird stuff and i remember just standing, feeling completely safe and comfortable, and looking around thinking WOW this is awesome!!!
My worst one is a recurring dream i used to have where i would be running through this valley to be faced by a huge valley wall on the side of a cliff, i would start to climb but as i get higher and higher the cliff starts to lean out so that im clinging on rather than climbing, eventually i start to panic and wake up. Not good - and no prizes for guessing i dont like hights. The dream itself wasnt too bad, its just the fact it was recurring that was the frustrating bit, anyone who has had them will tell you that it becomes a worry in itself after a few times.
So whats yours?
