Witch In Forest

I'm the witch that lives in a hut hidden deep in the forest. The hut (and the forest that it lives within) is filled with magical amazing secret things and has passages to many magical places.

On the outside, I'm just a regular person. The outside is just a front, a contact point between my world and the fronts of the worlds of other people.

On the inside:

A deep, dark forest with paths that lead to mountaintops, fields of flowers, stone circles, deserts, rocky beaches, etc.

Caves and passageways that lead deep into the earth.

Animals, trees, rocks, demons, and angels that share their wisdom and friendship with me.

A hut with shelves of magical ingredients and sacred treasures and other secret things.

What/who are you? Do you have a world hidden behind your front?
