The other night during a session I was about 30 minutes in, doing belly breathing and my heart rate started ramping up. This has happened before but this time the pulse or throbbing was moving to alternate parts of my body. The throbbing was moving down my chest to my stomach, traveling to my back then to the prostate area. It was very pronounced in each area and never in different locations at the same time. And also I felt if I could concentrate on the throbbing I could move it around to different areas (but just the chest, stomach, back and prostate). I dunno maybe i was just hallucinating. 🙄
