Ok so I had a lucid dream last night where i was on a school bus and as i was getting off i knew i was dreaming and about to wake up so i frantically started rubbing my hands together so stay in the dream since i was now lucid. so once inside the school as one stated to me before i wanted to summon someone so as i was saying "So and So is going to be around the corner".. I run into a hall monitor (lol).. She ask me where am i goin && as i notice this is a school where ive had quite alot of dreams in so i tell her as i've always said in a normal dream that i do not know where my class room is and she tells me to go get a pass. Ok now i know im lucid but i did not tell here look im dreaming i do not have time for this which i realize now i should have. So here are my questions..

1. Why is it that sooo many of us have the dream where were back at school and we DO NOT WHAT SO EVER remember where our classroom is and the bell has just rang.

2. when were lucid and a dream character "tells" us what to do.. how do we flip the script like i wanted to? is it that simple to let them kno that "Look dream character i kno im dreaming so leave me alone" ??
