Actually, I do remember one episode in my late 30's. My wife had twins. They were born extremely premature and there was a good chance they'd both die as we were at the extreme end of the survivability chart at that time - like by a single day of gestation and with one less day we were in the "recommend do not resuscitate" zone. Most compressed time of anguish I've ever experienced, stunned me for years. Both boys' bodies are growing good now, veeery quirky minds though.
Anyhow, studies had shown that preemies could benefit from just laying with the parents skin to skin, called "kangaroo care". So, I got to experience that with both boys one or two times! Wow, that was really something. I couldn't hold them or touch with my hands, just have them be laid on my bare chest. Very special to just love on them and feel them squirm around there a bit.
I thought, ok, I'm going to give them a little well wishing because the kid I was given was in the worst shape healthwise between the two. I closed my eyes, and concentrated on baby. I said mentally, "heal". "If you can take away anything from me that helps, do it! You have to grow and take food!" And I probed mentally.
Suddenly, I had a visual hallucination. It was a projected 3D scene of reverse images to the color of light coming through my eyelids. I could see some sort of movement of blobs rotating out, coming back. If they got too far outside my field of view they would fade and disappear. There was something like 3 visible blobs, a stationary one and two smaller moving ones. It was like I was seeing autonomic or mental processes in baby, visualized.
So I just loved on him for a bit and sat with that experience. And then I thought, maybe I can see my own processes if this is really happening to me? So, I said in my mind, "Show me what I look like". And the view changed!
What I saw was mostly out of my field of view, so many things were faded, but the blobs I could see were cycling in all different directions including away and back towards me and at different speeds. It was like a factory scene compared to my son's machine shop. I told him to take from that scene whatever would help, and the session ended soon after.
When I kangaroo cared with my other son I tried to repeat this experience and well wish him and communicate mentally, but I could not connect. That made me sad and secretly a little worried about this one's health, but I could not tell anyone my feelings because it was so odd what I had experienced with baby A. And was it just nerves and all my own imagination? Maybe, but it felt real.
