This is a combined recounting of two experiences that were shared at the same time.
My friend got stuck in a loop and started to freak out. It was his first major breakthrough experience. Although he participated with me over a dozen times, this time he went deeper than he had ever gone before. He yelled and I immediately opened my eyes from my deep journey and focused on grounding him physically and emotionally. He kept yelling "save me" over and over. I got up from my chair, walked up to him and realized he could not see me. His reality was completely blown apart and his ego was being picked apart and reassembled. That all familiar fear and the thought of "I'm stuck here, not coming back were present in his eyes.
As I looked at him, I was completely aware of what I was doing and what was happening, yet I was still mid trip. His face evolved from one form to another yet each time I saw the change, it ceased to be my friend, but I still recognized his essence and at times his new faces. He grew increasingly worried and asked for my help. At that moment, I asked him hold me close, so that he could feel my heart beat, help him ground him. At that moment, that's when we both recalled that we "phased" through each other, losing bodily cohesiveness. It was a seemingly in-between state.
At that moment, that's when reality started to show it's true colors. There were flashes of moments where we each took different forms of different eras. We sat at the table. There were twice as many objects in the room than there should have been. Two bottles of juice existed where only 1 should exist. Conversations as old men happened in clouds of smoke. The true nature of reality was evident to him now and it was too much for him to handle.
He slowly came out of his profound experience and was happy and appreciative of not only being back, but where he was taken. My visuals had already stopped and when we recounted our events, it seems as though the experience was very much as "shared" experience as well as a personally unique one as well. I existed in at least two different experiences at the same moment and so did he. At times each of those experiences overlapped and this is when the shared experiences were manifested.
I remained calmed and collected throughout the entire experience even though I had dosed high and was mid hyperspace. Opening my eyes to someone who seemed to be having a challenging experience was never a second thought. My first response was complete understanding of what was being experienced and how to help guide it to a more beneficial place. Even though my open-eye hallucinations were intense, I never faltered from kindness and guidance.
NOTE: We had set up precautions and monitoring with no participation unless danger presented itself. In terms of safety, you should always have someone (sober in every way) you trust nearby to make sure that if your trip ever goes south, you always have someone to help you. Even the most experienced entheonauts may find themselves in a new place that might illogically freak them out.
