I've been noticing, for a couple months, when I really relax and settle down I can feel, I believe, my pineal gland vibrating; I notice it when it stops or pauses and then it starts back up. It's pleasant... it's definitely not unpleasant. It's just so subtle I almost didn't notice. Now that I noticed it, I notice it a lot. Has anybody else ever experience this? If you don't know what I'm talking about, please leave the shill comments at the door.
