Lenny Bruce is not afraid

Last night, I had a dream.
In my dream I was in a hospital. On a high-ish floor. Let's say the 8th.
It was a typical day at the hospital. People dying. New people being born. People in the clinic with ingrown toenails. Everything was going pretty much like you'd expect.
I was doing a job that required me to do intense and important things like write up consults, fax medical records and email people to find out if they were available for meetings.
While I was pretending to schedule a meeting, but was actually reading something important on the interwebs a warning was blasted over the hospital intercom.
I say blasted, but I think that it was just that it was out of place and unexpected. Not so much that it was loud.
We were on alert. I didn't catch the color. All personnel were required to return to their stations and wait for further information.
I was at my desk and not officially personnel so I continued reading blogs.
People could be heard scurrying in the hall. There was a lot of yelling and panic. Someone came into my office. A patient. I helped this person (I think it was an elderly man) back to his room. In the process, I saw that people were genuinely horrified. Everything was a mess.
I couldn't find any of my co-workers. Presumably they were dealing with patients. Since I couldn't do anything on the floor and was just in the way, I decided to exit the floor and see if I could do anything in the other part of the building.
There was a crush to take the elevators, and what with my claustrophobia, I didn't want to risk it. I was on the 4th floor when the announcement came over the speakers that the elevators had stalled and the hospital was on back-up generator power.
I began sprinting down the stairs, but soon the stairs were full of panicked people running like the world was coming to an end.
I got to the lobby. Everything was a mess. People screaming, running every which way. Kids crying. The perfect scene of terror.
Outside, I saw that the sky was dark. Not like a storm. But unlike anything I had ever seen. Horrible.
I turned out of the lobby and took off down the corridor into the tunnel that runs between the main hospital and the MedCenter. The tunnel was strangely quiet. I began to think that I had abandoned some sort of post I didn't know I had.
I thought that of all the places for the world to end...At that point I knew, the way you know in a dream, that this was the apocolypse. The world was going to end and I was in a tunnel underneath a hospital. People were dying overhead. Terrible things were happening in the street. I was already underground. I was alone.
I tried to call home. But my cell phone didn't have service down there.
Then, I woke up.

What could that possibly mean? Have I actually already created the End of the World scenario for the hospital? Has it gotten to me that fast? That's got to be a new record.
