How true do you guys think this is? It is kind of scary.

PS I just had my first lucid in a while, and was getting excited to get back into it before I read it. Maybe don't read if you're easily discouraged.

Repeated thoughts strengthen the neural connections those thoughts use. The wonderful thing about dreaming is that neurons communicate beyond the path of least resistance which is the old, commonly used thought processes you use every day. When you're dreaming, that's when you get your chance to improve, to grow. The pseudo-random activation of the brain effectively tests the old deep-worn brain patterns and opens the door for better ones to form. By taking that opportunity to dream lucidly, you're using that chance not to improve your brain function, but to wear those same old pathways even more deeply. It's a deliberate impediment to growth of the mind.
