I think co-consciousness is meant to be a very good thing indeed. An important step on the way to recovery.

But it can feel quite unplesant. I don't much like it :-(

The more you are co-consciousness the more the boundaries between you and your alters start to blur. The more you are aware of all that they are aware of and the more they are aware of all that you are aware of the more integrated you are becoming as a person.

Of course it takes a lot of time and hard work.
But it is a very good sign indeed.
