By the way, not many new lucid dreamers realize this, but you are in total control of your dream.

That is as obvious as it sounds, but there is more to it.

In your case, you say that your dream was dark and you couldn't see anything. As simple as it sounds, all you need to do is think about everything being lit up, or turn on an imaginary light on an imaginary wall that YOU thought of in front of you.

Anything that is in your dream, the weather, the scene, the people, everything and anything is controlled by what you say and what you think.

Therefore, an easy way to sum up Dream Control and doing cool things is to simply "say these things, think about them, and totally believe they are going to happen."

If you want clarity, shout "clarity"! If you want something, think about it, and the next thing you know it will be there.
