Dreams have been described as dress rehearsals for real life, opportunities to gratify wishes, and a form of nocturnal therapy. A new theory aims to make sense of it all.

I don't necessarily disagree with the the essence of your article--that patterns of addiction and other behaviors can get "embedded" in the brain vis-a-vis the limbic system; however, calling the limbic system the "lizard brain" is really a silly mistake. "Lizard brain" refers to the oldest part of the brain, the brain stem, responsible for primitive survival instincts such as aggression and fear ("flight or fight"), whereas the limbic system is responsible for, among other things, our emotional bonding to other creatures--other humans such as family members and friends, and non-human pets. Dogs, cats, and all other mammals have a limbic system, along with humans. This system represents a higher level of sophistication in brain function. Reptiles do NOT have a limbic system in any meaningful way, and while I understand that you are referring to the colloquial use of the term "lizard brain" rather than its exact scientific meaning, I have never heard anyone refer to their emotional brain in this way, and I read a lot of personal growth authors. People talk about their "lizard brain" when, for example, they are suddenly overcome with road rage, or when they fear someone is making fun of them and they react with hostility rather than diplomacy (because they have unconsciously construed the insult as a threat to their survival). That's "lizard brain" in action. Not when they find themselves defeated by an unhealthy and long-entrenched emotional pattern. That is indeed the limbic system at work--the seat of memory, of emotional gratification, etc.--as you note. However, people don't call that phenomenon the "lizard brain," (unless they are your patients/clients and you've been teaching them to do so.) Please rethink the idea you are putting forth in your first paragraph.
