I found this an amazing thread, really great to hear about others experiences and more information about it. I'm also sorry to hear about the hard times you guys have written about and shared. :hug:
I'm slowly exploring this topic myself, and learning more about it.
In my experience I would say that I do interact with various 'parts', but that they don't overpower me, or I don't loose full control. They are all characters, and are spiritually connected, as I always read a lot of spiritual books growing up. For example, one character is my more creative and rebellious side, another my more geeky side. We keep in contact and I take inspiration from them, of how to make my life more fruitful and interesting. Its always positive though, and makes my life more vibrant. For emotional and creative things my characters are all female, for more rational and active things, they are male. Some are scary looking, but all are kind overall.
