Rather disturbing...

I had a particularly disturbing dream last night. Once again, it involved people I've lost touch with, though more recently. Maybe there's some kind of message here. It's probably pretty straightforward all things considered.
I started out in a garden. Stone walls covered in ivy with a moss drenched birdbath by an archway. It looked pretty old, and while I've never been there it felt familiar. There was a headstone sticking up from the ground to the right of the archway.
Standing on the grave was a former coworker of mine. I wouldn't exactly call us friends, but we were friendly enough. She was a tanned latina, brown eyes, with dark auburn hair that reached to the middle of her back. I've always thought of her as bright, and if she didn't have a boyfriend, I might have considered asking her out.
But that's neither here nor there. She's standing on the grave, looking down at the headstone. Neither of us has to speak for me to realize it's hers. I knew that before I walked up and read the name off of it. She turned to me, and spoke. It was happening today. Maybe soon. Then others approached, from all around, surrounding her. And the next thing I realized, I was being pushed aboard a rail tram. If you've played Half-Life, then you have a good idea of what it looked like. I found myself alone in it as it wound through a cavernous tunnel, shaped like a long diamond. Upon exiting, it approached a hospital and stopped at one of the upper levels.
The place was bustling. Patients waited on chairs and benches, nurses walked briskly across the carpeted floor, a doctor or two leading a stretcher into rooms. And there she was to my left, lying in a bed. Against a window in a room this busy. She was accompanied by one or two coworkers, and a few people I didn't recognize.
The two seated in chairs at the foot of her bed where girls I knew from the fencing club. People I didn't think she would know, though in a place like Pasadena, anything is possible. They made way for me when I walked up to her. She said it was time, and before I could make a reply, my alarm went off.
Hours later, and it's still quite clear in my mind. I wonder what that's about.
