In most of my lucid dreams, I think the DCs representing people I know are real people sleeping in the same dream with me. Not sure why...I think it is so real you assume you are in a real place so if you are there and real the others must be too. Otherwise I am fairly rational in my actions, although definitely uninhibited and feeling maybe a little drunk. I would suggest intentionally engaging your senses..touch and feel, listen, etc. That makes you more aware and lucid.
