New York?

I dreamed the combination of a Big City (Like New York or Tokyo) and a Marine Base.
At one point there was even a garden of skulls somewhere...

ehh.

It seemed like it took place in the distant future. The world was at peace, and but the military was desperatly needed to keep things in place.
And i felt like a different person. I had a friend who lived in Sky City, a whole set of information that this person collected over her life time and a whole different person. I woke up with an ache.
