I had a weird experience at work on Thursday. Around 5:30pm, I started to feel really sleepy. Not just normal drowsy, but really, really sleepy. I also felt really heavy and dense, like a 10lb bag being filled with 15lbs of product. At times there was a feeling of something immense within me, unfolding. And yet, at the same time I felt rather light and graceful. It lasted about an hour and then settled down.
It was still there on Friday, but wasn't nearly as noticable. Not sure what it was about.
