i know this has hapend to me on more than 1 ocassion 1 time that i recall i was dreaming i was in a court room and my mum was the judge and she was sat their holding that hammer thing up in the air for wat seemed like ages all of a sudden she hit the table with it at the while shouting my name i then woke up to find my mum had knocked on my bedroom door and had shooted me. now i asked her how long she had been trying to wake and she had only just shouted me but my dream lasted for like 30 mins at least
