Had an LD Last night, i was chasing my girlfriend thru crowds of people and we ended up in a shopping mall and i relized it was an ld, there was a blonde woman walking thru the store long blonde hair some cream t-shirt on with cream 3 quarter lengths on her bottoms and she had black high/strappy shoes, didnt see her face but i told my girlfriend it was a dream and she said tell her *the blonde woman* i said "hey" and she wondered off so i left her and decided to fly, i was flying around the mall and went one floor up, when i got into a fight with what appeared to be robin williams out of the night at the museum

and i suddenly lost lucidity and the dream went on, how can i stop this happening?
