I'm a little confused about this subject. While lucid, I have asked my dream characters questions such as:

What's your age/name? (I ask this to friends/family, not strangers)
What day is it?
What is a dream?
What is my purpose?

I repeatedly ask them these, but am never returned with a straight answer. (I've even been laughed at when I asked that last question.)

That got me to thinking. Dream characters are essentially your creation, created by your mind. And when vividly lucid, they respond to you however you wish. For most questions that I ask, I know the answer within the dream, but for some reason they don't. Why is that? They are my creation and part of my mind, thus, they should know.

Unfortunetely Stephen Laberge left this area out of his "bible". I was wondering if any of you have any thoughts about this as well or maybe some links to some studies done or essays.

Cheers.
