I do believe that getting hung up on the words people use to define the mlc experience is counterproductive. I work with glass. When glass shatters, the best way to put it back together is to put it in a kiln (oven) and bake it until it fuses back together. As an analogy, baking is fairly accurate, because until any dissociated parts "fuse" or get integrated a persona is fractured.
My point being that saying that the word "bake" or any other word is over simplifying things is simply not true. Not everyone wants to delve into the mysteries of the psyche, or even CAN depending on where they are in their LBS journey. Some of us (that would be me) use humor to get us through. Implying that because someone uses a word you (the generic you) would not use means they are over simplifying is rather over simplifying, imo.
To the topic at hand, what is MLC? Since I didn't have one, it LOOKS like someone reached a point where enough things had happened in their life where they can no longer sort out what they used to believe and experience from what they currently believe and experience. And quite honestly, I think it could be caused my multiple factors, from a severe chemical imbalance to FOO issues to childhood issues (not necessarily FOO), to a true identity crisis where everything they were told was the correct thing to do no longer jibes with where they are in life. And they all manifest in a similar way either due to the individal (who may or may not have lived with some sort of chemical imbalance, or personality disorder or neurological disorder all their life, but we're able to hide it) or due the fact that each one is a crisis in its own right.
Like all the virus' that LOOK like a common cold, but aren't. Like ailments that LOOK like they are caused by one thing, but are really caused by another.
One person's perspective, which allows for other people to have their own perspective.
