Hello, Volgerle.

Regarding bliss - according to Kurt bliss manifests most strongly when you get much closer to Source than you usually are. That is one way to experience bliss or even ecstacy. It fits very well with your surprise at the vividness of everything.

The inner senses most prominently active in this experience are probably vibrational touch (the communication) and immersion (the intense vividness of the experience).

One possible explanation could be that you never before had experienced your astral body so vividly, fully immersed and with that degree of lucidity. The information exchange with the other person hints at the astral body - you describe it as if feeling/emotion was the "carrier medium" of that exchange.

The ability to exchange information through feel/think (how Kurt calls it, NVC in Monroe-speak) expands during developing the astral, mental and causal bodies. It's an unfolding. With the mental body you learn to translate exchanges into pictures, and with the causal body you absorb the information in a more direct way. Think of Robert Monroe and his ROTEs. They demonstrate his increasing ability to absorb and understand instantaneous information exchanges. Kurt classified that level as mental and causal in the introduction to his new book. That would be taking the vibrational touch to the next level and developing the information sense.

The second scene could have been a switch to another energy body - with less active inner senses. This would explain the strong contrast with the earlier experience - grainy vision, less input from the inner senses. I wouldn't exclude that this could have been the etheric body. The bodies need not be developed equally. I think the quality of not caring either way has also been reported from NDEs. Usually the bliss comes afterward, so you might be right about the order of recall.

So, in total my first guess would be you were in your etheric and astral bodies. The astral body is a very powerful vehicle which allows for rich and detailed experiences, but it depends on its development and the degree of immersion. When you have lucid dreams, you usually have a well-developed astral body to begin with.

Cheers,
