I've never had the urge to sit on floor, but my therapist did once sit on the floor in front of me to bridge the distance between us. We usually sat side by side on the sofa, but that day I was feeling like a pariah, and did not want to be near her for fear of contaminating her. I sat on what I called my island, a love seat that she was forbade to sit on. After trying to cajole me for a while to come sit next to her she got up and sat on the floor in front of me.u I surmise she did not want me to think she bought into my feeling that I would contaminate her. She did eventually reach out to touch me, but I told her not to, and she acquiesced. The air condition was blowing directly on her, and she does not suffer cold well so she went back to our seat. 10-15 minutes later I followed, and allowed her to hold me for awhile.
