When I was in group T they told us to lay down, try to slowly relax every inch of our body and imagine we were some place where no on else could be seen.

I imagined the beach, early in the morning with a slight breeze. I pictured myself relaxing on a blanket with the sun shining on my face and the cool breeze blowing across me. It works. I can get so into my "safe Place" that I can feel the warmth of the sun and the coolness of the breeze.

I hope this helps you in some small way
