I don't what any of you think about this, but I have been looking through this forum and reading everyone's dream journals and dream recalls and what i have noticed is that whenever someone is lucid and they go up to a DC and try to talk to them about the act of dreaming by saying something like

"Do you know that you are just a figment of my imagination?"

or

"I am dreaming and you are not real, what do you think about that?"

99% of the time they usually either

1. Do not reply
2. Become hostile
3. Reply with some stupid answer like "well i guess that means the cat ate its own seesaw..."

I think this is a sign that your sub-conscious does not want you to know the secrets of dreaming, or maybe isn't fast enough to come up with a genuine reply quick enough. What do you all think about this?
