I don't necessarily think that rewiring the brain in such instances as Caroline mentioned would necessarily be a bad thing. In each instance, you are experiencing something different that I don't feel can really be of any harm. Perhaps if you experience a very traumatizing event and your brain is rewired so that you are less able to cope with future stressful events, then it could be harmful. But as far as unconcious experiences through dreams or other thoughts, I don't feel that this could be harmful.

This idea that the brain can be rewired is also a very important discovery for it shows that cognitive behavioral therapy can acutally be very successful for all of those people who may be skeptical. It also gives credibility to self help books and meditation and other such practices that seem to often cause controversy.
