My most memorable? About two years ago, I was sat outside in my garden in the summer, meditating. After a while I became antsy, I couldn't sit still or concentrate, but I didn't know why.
Then I watched the sky darken and heard the first, faint rumble of thunder in the distance...
I could feel the energy growing in the air, my hair literally started to stand up as the storm grew closer and closer. I stood up and held up my arms towards the sky (luckily I wasn't the highest point

) and cried out... and then the heavens opened and the Goddess' sweet rain poured down onto me. The thunder boomed and shook the very ground while I danced wildly, round and round in the rain. The lighting seared the sky and the energy around me and inside me was so intense it was almost unbearable.
When it was finally over I dropped to the ground and returned all the excess energy to the Earth. I just lay on the soaked grass for so long afterwards....
