No, that is not what he said. He said what we see in those experiences are spirits, for lack of a better word. Life after life. Survival of the soul after the body dies. But the next world, being less substantial, less of the flux of atoms, is a world where thoughts are more immediately creative of your experience. There are levels to the next world, he said; the first level is like a copy of this world (or vice versa) and higher levels are without form, more like pure consciousness.
Dr. Fontana's experiences were a lot like yours, except that he was in contact with those lights, etc., in a controlled setting with mediums that helped the researchers to contact the spirits. It's not so much like a thought, but like our consciousness which has thoughts.
It is something like that, with ghosts. I am feeling more like that myself, now that I am in my sixties. Although I feel younger, some of this internet and i-phone stuff is getting hard to keep up with. The language people use gets hard to fathom, and terms are used which apparently everyone knows but I don't. Even here it happens. I am glad at least that pop music is not as incomprehensible (and ugly
) as it was a few years ago. But mindless show biz has taken over the TV talk shows and even the News broadcasts here in the USA. There's no more talk radio, and my confidence in listening to the radio for current music is gone. And there's the fact that we had made such breakthroughs in spiritual and psychic things, and yet now it's as if it all never happened, and people just ignore it and go back to materialism just like in the 1950s. So, for me, today's world is getting stranger.
