I've told this story before. Once early in therapy, at a night-time session, he asked "what can I do to make you feel safe here?" This was in preparation for a big disclosure from me, something I had been trying to tell him but had been unable to. I had had this dream where he and I were really safe in his office and in it, the light was a lot dimmer. So I tried to recreate that in his office (but didn't tell him about the dream). I just told him I would feel safer if it wasn't so bright. So he turned off the light next to me. Still too bright. Then he turned off the light by his desk. Still too bright. Then he turned off the lamp next to him, and it was pitch black in his office. Neither of us could see a thing. I think he even asked "still too bright?" or something like that, lol. I started laughing hysterically, and he joined in.
