This experience started after I had already been asleep for a while and had awakened to find that I could not fall asleep again. I was aware of laying there and suddenly I was hit by some force or other that knocked me sideways. I felt as if I was tumbling, but I was also aware of my body in bed still in the covers with my arms at my sides. I was aware of the signal (?) I have heard before that my awareness had shifted, but it seems at this stage that I have to grab onto this signal, so to speak, to have any experience at all. In the past, this having to grab the signal has been hard. This time, my instinct was to chant Aum namah Shivaya- Aum namah on each inhalation, and Shivaya on each exhale. Doing this seemed to grab that awareness of elsewhere and bring it more into focus.
This time, all of my sensations were much lower in frequency than past experiences where I had usually tried for higher and smoother vibrations. These are low to the point of being aware of individual vibrating molecules. None of this is easily described. The chant of Aum namah Shivaya focused the power. Putting this chant into more of a melodic chant helped increase the focus. Dropping it occasionally to simply Aum seemed to draw the focus of energy more into my brain. I just remembered that early on in this, I could almost feel my lips moving in the chanting and was aware of my vocal chords moving. At the same time I knew this was not really happening physically.
