lucid dreaming

start out with a dream that i was with my friend, the we were at the bottom of the river, got out but had to save a friend who was running out of breath, then almost attempted CPR, while a person came and asked,'are you guys alright? I saw the car go down the river' and then i thought to carry  my friend instead of letting her walk.....NEXT DREAM...some place where i was planning to go perform a magic show, everyone i know was here, and there was also a sci fi stands everywhere, performed the easiest trick with birds, then left the show and passing by a friend who was at dream #1. Then when i went to the place where it looked like scifi-convention, or something, someone asked me to make an intense sci fi website, and that kicked me out of the dream
