Question regarding the Mastering the Model

Hello! I was watching the video on mastering the model with Michelle and had a question – starting around minute 51.26 of the video. Someone wrote in about feeling fear and Michelle said you could put “I feel fear” in the C line. This felt completely contrary to what I thought I knew about the model. It’s been on my mind and I just wanted to ask about it. I thought C line was “just the facts” – totally neutral. Something that could not be disputed or subjective. Is a feeling ever a circumstance? Thank you for your time.
