Eh several places for me actually.
>My local church, I could be very stressed out, yet when I go there I feel calm.
>My room. I have all sorts of ponies everywhere. figures, plushies, and posters. Also I can relax in it.
>Christmas time. The music, the decorations, I find it all relaxing. Sometimes I'll sneak in a Christmas song any time (I'm weird, I know :P)
All I could think of at the moment.
