Re-occuring dream ?

I was walking with a friend down the pavement (can't remember what we were talking about) and we had to cross the road. Whilst crossing the road my friend is knocked over by a car (but it doesn't hit me) I tell her that I will go and get help as noone is around. I don't go to the nearest door, but a particular door around the corner. I knock on a door and an old woman dressed in black answers, I'm out of breath and panting, and say that I need to call an ambulance for my friend, she tells me that I will get help, but I have to choose the right door and disapears. I'm in a square hallway with a door to my left, right and in front. I choose the door in front and find myself in a theatre (back right hand corner) standing at the top of the stairs looking down on a lit up stage (i'm alone). I run down to the stage and start calling for help, but noone hears me, as I reach the middle of the stage a trap door opens and I fall into a prison with a high cealing, and bats flying overhead. cont..
