Not necessarily "lack of control," should the term even have much bearing here. There is some interesting stuff (as opposed to research or work) about "lucid dreaming" which has a lot to do with taking charge of your dreams. You might also have a look at material of "senoi dream work," which talks about a cultural approach to dreaming as shared experience — very different that what we are used to.
When I have some time, I'll try to write at greater length. Working with dreams is very rewarding in many ways. They can teach you a lot about yourself, whether you think of them as sort of chemical non-events or see them the the Royal Road to the unconscious, as did Freud.
It can be a useful thing to keep a dream notebook open by the side of your bed at night, and to write down what you remember of your dreams when you wake. With practice, you find that you remember more and more of them, and they can be a marvelous resource for poems. It's often helpful to have a series of dreams to look at if you want to think of interpreting dreams, depending on which style of dream interpretation you use.
That's all for now. Yours, Bob Kaven
