I'm not sure of the question. Is this what you mean:

A depression I had a few years back was a new state for me. It was near catatonic. Somehow I was able to eat and go to the bathroom, but other than that, I was blank. Every so often I'd come to and howl and cry but then back to nothing and staring. It wasn't pleasant but somehow time passed and I didn't notice much of anything. It was weird. Then I woke up. I was in that state for nearly 6 months.
