Experiment: Lucid Dreaming

This is an experiment to be conducted in part while you are sleeping.
Throughout the day look at your left hand. Whenever you think of it, ask yourself:

"Am I dreaming right now?"

For an answer, look at your hand carefully and tug one of your fingers. If the finger retains its shape then you know you are in this consensual reality.
During the night as you sleep, the procedure is the same. If you begin to suspect you are dreaming remember the experiment and do it within the dream. When you pull on the finger, you will see it extend and you will instantly know that you are in a dream.
At first, the objective is simply to "wake up" within the dream and experience it from a lucid point of view.
Later, as you become more proficient, you will set objectives within the dream and remember what it was you wanted to do once you got there.
