It is easier for me if I get lost in working on specific incidents or memories to such an extent I forget that T is there and comforting. Think about an incident you don't like to think about :-) and work on that and forget where you are in reliving that pain.

Listen for triggers in what your T says and follow the trigger! That's generally what T's do, they are trained to follow your "emotions" (as opposed to talking about the weather :-) so if you express any sort of affect or feeling word, they're on it to "deepen" it.

Do the same in reverse, paying attention to things your T says that "frighten" you or make you anxious and deliberately follow up yourself on what your T has said, get curious as to where the feeling is coming from and what it means, etc.
