It appears that folks here should learn to control their night dreams . . .

My siblings and I are lucid dreamers from childhood. One of the tricks is to recognize that you are in a dream and what the constraints are. For example, in a lucid dream I launch myself into the air because I can swim in it. I know I can so I attempt it. Likewise, I can perform any physical exercise in a lucid dream without tiring.
My mind cannot invent text as fast as I can read it, so I know to avoid trying to read a sign or book in a lucid dream. If something goes wrong, or is otherwise annoying, in a lucid dream I know that I have control and have touchstone places and events that I can return to - as a way of resetting.
My brothers and I dream in color with surrealistic sounds, smells and so forth. In school I read a psychology of hypnotism textbook and learned that people like me are easily hypnotized. One of my younger brothers sleepwalked as a child and it was my responsibility to keep him away from the stairs and make sure he really knew where the toilet was. I could control him, with his eyes wide open as he moved around, by gentle voice command.
Such memories. But I far prefer daydreams.
I also sleepwalk and have some control over my dreams. But I don't believe I am easily hypnotized. I fail all suggestion exercises (Why, yes, how did you know I was thinking of a green elephant? Green elephant?!? I was thinking of a gray emu!)
