Exactly. If I find myself in a school taking an exam I did not study for I have to realize I’m dreaming, remember I have total control of my surroundings, stand up, walk out of the classroom while thinking about where I want to go. Sometimes the dream throws roadblocks like “I can’t find the door out of this classroom.” The trick when a roadblock happens is to remain clam, remain confident, and find an alternative “Oh yea, the door is behind me.” If I begin losing control I often begin losing lucidity. If I exert too much control (Let’s just walk through the wall, I can do anything) then I will wake up.
