Shadow Cast

It seems you've got a glitchy problem on your hands.

First I suggest you "Call Cab" from the phone box and select any option available (in this case Magic Town, or studio town). Let's say you picked magic town, for sake of example, once you are at magic town try clicking on the phone box again to see if you can return home.

If that doesn't work, try going to yet again a different place until you are able to go home.

-Hope that helped.
