Grounding exercises, I'm guessing you mean the Ending: Harvesting Qi exercise mentioned in level I? If that's the case, come to think of it, I didn't do it on the day of the strange experience I mentioned in my 1st post. I'm feeling rather silly, because I know it says to always finish with this exercise. I haven't done QI since that occurrence. I will try your suggestions. Thank you so much for responding!
