work elevator

I dreamt that I had left for work. It seemed as though I was in the distant future, and I worked in a very large hospital. I had to park in the parking structure initially, which was a large dark building with many floors, connected to the hospital. I drove up a few floors and I thought one person was leaving, but they were taking their time, so I decided to move on. I kept driving and found an empty floor. I wasn't sure if I was supposed to be there, as the floor was very dark. The floors of the hospital were many stories high and many stories below ground. The elevators seemed to go horizontally as well as up and down. Some nice employees were on the elevator. I wasn't sure which way to go or which button to push, so I told them to go ahead and push where they needed to go and I would figure it out on the way.
