Thanks JohnMac - appreciate your response.
I havent meditated using Dr Joe' meditations since the day I posed, when I had the worst meditative experience of my life. I thought I had experienced resistance before and just 'allowing it' helped - but, well, nothing could compare to the screaming discomfort I experienced in my last few Dr Joe Meditations. I think the severity of the discomfort started to turn my blissful experience of meditation into something that made me feel worse afterwards.
However, it really does help to know that other experienced meditators have felt something like this (and gotten past it), and I do agree, probably was just a LOT of energy moving around, making me NEED to move about.
So, I'll give them another go! Thank you - appreciate you taking the time to support my practice
