I don't see what's so psi about ebing able to control your dreams. Or whats important about it for the matter.
Que Mage answered the importance of it. It's not really that much of a psi ability as it is psychological. Psychism can make itself known in dreams, but otherwise you're dealing with psychology. It's about as psi as hypnosis.
Don't get me wrong; I love hypnosis and often use it as a gateway to psychic phenomena, but it isn't psychism. It's a psychological mechanism that can be used for many purposes, some of them psychic. ^_^
Hmmm...maybe I should be a psych major, if nothing else for an excuse to research parapsychology.
