We once had the most amazing and vivid dream about our system structure and while we recognize it was a 'dream' and not an objective reality we have held on to this dream as a way of making sense of our internal organization.
And yes, there was a safe area where the littles could hang out and be taken care of by the internal helpers. Interestingly we couldn't see inside this area 'because it was only for the littles' (and the ones that nurture them). So it is safe from us meddling adults ones too.
