Poor girl, these phantoms, although perfectly normal, can make them very miserable. :( As the others say, take away her hedgehog, and any other toy she fancies when she's like this. You're going to have to be 'cruel to be kind' and force her out for lots of exercise, and cut her protein levels. Don't give her time to brood, but rather be very enthusiatic and public-school 'jolly-hockey-sticks' with her, and she'll be a lot happier a lot sooner.
