What is intuition?

Hi Brooke, I am wondering if “intuition” or “intuitive nudges” fit somewhere in the model? I understand that according to the model, feelings come from thoughts. But what about those times when you are in a situation and you feel that heaviness in your gut or your heart starts pounding and these vibrations seemed to have come from nowhere? Or in the instance that you meet a new person and can “feel their energy” or when you walk into a crowd and you know “instinctively” that you should leave right away, even before anything “bad” happens?
Thanks Brooke, really enjoying my first month in the program!
