I get migraines and when I would have a migraine in session my former T would turn the lights down or off and we would just have the natural light at that point. It did seem to help me open up. Current T I see later at night, so there is just a lamp on and it is darker (though not dark) in her office. I talk more with her than I did with former T so maybe it has to do with that? Not sure. Something to think about. HUGS Kit
