What does this dream mean?

Well I had a nightmare that I was strapped onto a gurney in a hospital and instead of going into the operating room I start going down a steep slope and then the hospital started looking little by little like hell and the paitents looked like demons. Then the doctors pushing my gurney morphed into demons as well and yelled "welcome to hell" and while I screamed and tried to get off the gurney they started laughing maniacly and flew away. Leaving me and the gurney engulfed in flames....... I've never been in the hospital for surgerys so don't say that it was my nervousness. I want to know what this dream means becuz I couldn't sleep for a while after it
