To anyone 'outside' her mind, the woman will merely glance at the ball a moment. Her body will feel a compulsion to put the ball away in a pocket and then go quietly have a seat by the pond. Given that her mind is elsewhere, there should not be much resistance...

'Inside', deep in the comforting darkness, the woman meets a little fox with three tails.

Hi! Thanks for coming to rescue me!

he looks around

It's really not that bad a place, but it's empty.

A door appears behind her, vague and ill-defined

I can't open the door, but maybe you can. Then we can escape!

Of course: it's not true. That's the door to her own inner space and once she opens it and lets the little fox in, he will be able to take control!
