always seems to be my head vibrating/shaking but it has lots of of pressure on it! the pressure makes me stop meditating because it pulls me out of focus. i wonder if its got to do anything with AP. i have not went into a meditative state yet but am still learning. also i was laying down before and just relaxing breathing sub-consciously and then the next minute a unexpected picture pops into my head. i have a cupboard next to me but the cupboard popped into my mind but the weird thing was the cupboartd started vibrating:shaking, the picture was vivid in my mind, can anyone help? thankyou.
