Isn't that the story of a young child with an unpredictable caregiver.
One minute they're all over the baby, the next to gain control of their own wounded child they're unavailable
The baby doesn't know how to regulate.
Wants to be nourished, but if afraid of how it will be met. So pops, it's head back in its shell.
The dream features all aspects, of yourself. The part that could nurture and the experienced of not being nurtured, the internalised mother.
Just wait until your session. See what pans out. Until then it's all fantasy.
