My safe place is part real and part fantasy There is an old house in the country a few hours drive from where I live, that I would love to own. It is abandoned and falling down. But it sits like a little jewel in the middle of a meadow,with a big tree beside it to shade it. There is a lake nearby and the house is far enough off the the road so you can't hear cars.
That is the setting. And I have imagined the house as I would renovate it if I could ever buy it. A big open space with a big open hearth fireplace downstairs, and a nice loft upstairs to sleep in.
When my previous T used to get me working with my inner kids, I would imagine us all in this place. Sometimes hanging out on the floor by the fireplace. Sometimes out on the big porch watching ducks on the lake. When I need to get back into the here and now I put everyone to sleep in their own beds upstairs.

Well, that is my place. Not like any place I knew as a kid. I guess my own safe place has really always been in my own imagination...

I am sure given time that you will come up with something that fits for you.
