Is It Possible To Alter The Subconcius Through Lding?

Is it possible to alter the subconcius through LDing?

For example: if being violent in lucid dreams, can it make one's subconcius more violent?

I believe the answer is yes.
If you are reacting to negative emotions such as hatred, fear, and jealousy than it can strengthen your conditioning to reacting to these emotions in real life.
And if you are equanimous and compassionate in the dream, it can help your tranquility in real life.

wasn't there a thread about someone who had a "dream computer" wich he could use to reprogram himself?
