I would not normally dream log, but this was so scary and weird that I had to.
I was in hospital, visiting a very good friend of mine, who was dying (note, none of my friends are currently dying, this is an invention of my sick mind). I stayed there for what felt like hours until finally they died. Now, I cannot quite remember the circumstances, but I had to have an operation while I was in the hospital. I was taken from my dead friend and made to lie on a hospital bed where a nurse came to give me the anaesthetic. I could feel myself falling unconscious, and as my eyes finally closed in my dream I woke up.
I lay in the dark for several minutes wondering where I was, and was I dreaming or awake. It took me five minutes to rationalise in my mind that no-one was dead, and I was ok.
