My subconcious.. i can sometimes talk to in a dream. I ask it sometimes if i am allowed to do certain things, and well many times it says no. It has taken many forms in my dreams. I've only begun to notice it recently.. but although i usually have total dream control.. their are situations where my subconscious limits it. (another interesting thing.. i had a conversation recently with it.. and i remembered a few things from my past)

So yeah.. i believe your subconsious plays a huge role.. and your mastering LDing will depend on the fact of whether you can agree with it, or blend the line between consious and subconsious.

This explains why you never have "full" control.
