The Peak Experience--Shared vs. Alone

A central element of my research project is the "peak" experience. This is the intense reaction I get when I cross from the Negative Zone to the Happy Zone, or vice versa. You can see a video of it here. Most of the time I drove alone to the peak. My girlfriend at the time helped me create the video. She was behind the camera at the time I crossed the peak. She says that she didn't feel anything when I crossed the peak.

Last July, when vacationing in Utah, I brought two of my friends along with me to the peak. They are both experienced in energy/psychic phenomena. When I went through the peak, they experienced intense reactions, too. One friend could visualize the peak traversing the area we were in. One time, I walked the peak with my arms around each friend. They were shaking almost as much as I was.

I think that their reaction was secondary to my peak reaction, but nevertheless it was intense for them. I'm curious to know if anyone else experiences the peak, either alone or with others.
