I've always had a mortal fear of anything medical, so this scared the hell out of me.
I was at my local hospital due to get some kind of injection, and I just kept trying to find the exit, as I knew I wasn't supposed to have it as it would cause me terrible pain. However I go one way, and reach a dead end, so I go back, reach another dead end, and the process just keeps repeating itself, until the amount of rooms I can get into gets smaller and smaller. Eventually I get stuck in the mortuary, and what sounds like the voice of someone I know really well tells me as I refused, this is where I belong, and I can feel myself dying and being put in one of the freezers whilst I'm still alive. I try getting out, but it's like the freezer door never existed and I'm trapped in the dark and the cold, using up all the air.
That's when I woke up.
