My girlfriend has a pretty enviable gift; she has some incredibly vivid dreams. Whether she's actually lucid or not, her body will react to the dreams naturally - talking, arguing (about a whether a honey badger ate honey), running (after little people that she wanted as pets), and for her wet dreams - dry humping, getting wet, even masturbating in her sleep. Orgasms won't even wake her up - it's all her dream as far as she's concerned.
