Sleep event

I am not sure what order these came in. 1. My mum came in my room and woke me up to tell me what she was going to do today (weekend) (After I woke up properly I reality checked and thought to myself, 'I do not remember what she said to me'. Went out and checked her room and she was still asleep.) 2. I was with two other guys, and we had to get down a huge sandy/rocky hill. We tied a rope to a ?rock? and let it fall. We noticed it only went part-way down, and there was a colour change in the sand where it ended. One of the guys said that that was where the 'magnesium' ended and we would have to use a different kind of rope for the rest of the way. So we tied a red rope to the end of the normal rope and climbed down. There were a lot of sharp rocks at the bottom and I thought, 'Lucky we did not run down here'. This dream sort of morphed into my nightmare, I think I was supposed to be with one of the guys 3. (Nightmare) This guy and I reached our destination, (the scenery reminded me of Atacama Desert in BFBC2) we were sort of just instilled with fear and images of the ?teenage girl? flashed up a lot. (Its a bit vague how I knew it was a nightmare at this point). I 'woke up' to find myself in a dark room next the the other guy, and the girl in front of me. She said something like. 'Oh, you woke up. We will just have to use a different method then.' I saw her move over to a selection of sharp and painful surgical items. By now I knew it was a dream but I was too scared to become lucid, so I decided to wake up. On reflection, I should have stayed in the dream 'cos no matter what happens I am safe.
