I don't know what your watcher does but ours are not scary. Ours just keep note of everything kinda. Like they know the system. But they don't have feelings about any of it. Like some alters hold emotion, some hold physical sensations, and 'watchers' hold the knowledge. Our ones that know stuff like that are not scary at all.
What is scary about what you call watchers for you?

Our wise ones say ' go with what is' meaning forget a label or a name and just work with the reality of your own experience. That's what matters to you - not whether or not you fit a set of diagnostic criteria that someone else wrote in book. Their words can not invalidate your own truth.
