Happened to me with first path A&P, and still happens sometimes. It was a feeling of pressure that traveled up my neck through the back of my head, while I was having vibrations that left me shaking all over. Other than the excitement of having it happen, I’d say it wasn’t pleasant or unpleasant.
Vibrations: good things to notice clearly, to notice how fast reality goes and, thus, your mind can go. Notice how everything vibrates like those vibrations do, space, you, not you, everything.
I actually posted something about this and wanted to have people's opinion about it, here's the post:
"Hey guys I am dealing with a little dilemma here. For a while now whenever I applied minfulness (to see when phenomena arise and pass away) I would sense vibrations when I note, sometimes regular other times irregular, sometimes fast sometimes slows (depending on how I focus). Such vibrations can happen anytime, sometimes it seems that I need to focus to see them which make me believe that I am the one generating them but sometimes I do not need to make them happen for them to occur. One thing I noticed is that when I focus lets say on the nostril somehow I can make the vibrations occur which make it harder to sustain a samatha-like concentration but I can also make them disappear which facilitates concentration. My doubt is that sometimes I get the feeling that I am the one making the vibrations even though I think I am noting. "
I think it is close to what you are describing. What do you think?
Yeah, when I get to a certain stage in my meditation, I can focus on the area just below my belly to induce the vibrations(or 'sync' them with the breath to create bigger vibrations). But they usually happen on their own.
However, I don't practise noting. I practise the samatha practise outlined in TMI.
