Amnesia the dark descent part 1

I snuck thourgh the room and peeked around the corner it was gone it had disappeared. I ran into a room with a trap door. there were ropes leading to a wheel. I tried to turn it but it didnt budge,I saw a stick in the pulley I reached up and pulled it out. I turned the wheel and dropped into the trap door. I was in a large room there was a door to my right and a passge leading to the left. suddenly everything went black and the room was filled ankle high with water. I saw splashes of water coming towards me and something scratched me I quickly jumped onto a box I had to throw something to distract it.
