Thank you Florence.
Prior to getting to your questions, let me point you to two various metaphors I relate to in my own 'out of body' experience with a loss of vital signs.
Hologram. There is a free ebook title
"From the Stars." Type in hologram in the search and it will take you to page 39. Read the metaphor about the simple explanation of what a hologram is and see how that relates to where Jesus reference a scripture that says,
"Ye are gods."
Collective Unconscious. Dr. Carl Jung came up with a great theoretical equation in building a bridge between the conscious and the unconscious.
When I was 26, I was trying to define the difference between the 'conscious' ego point of view and identity and the 'unconscious' spiritual point of view and identity. I told a friend that my human mind just had a reflection like a mirror of what my spirit took part in outside my human body and human point of view. There was a point when my spirit got into that 'hologram' point of view and looked back on the planet earth. In that 'god module' point of view - it had sight off all six billion people on the planet earth and knew every single living, breathing thing. People, plants, animals - everything. The entire history of - leading up to that point in time. It was a 'mystery' defined by incomprehensible to the human mind. It was beyond scope of any microscope in human form. I had another 'out of body' experience during a flat-line moment and 10 witnesses saw it. They wanted to know where I went and what I encountered. I told them,
"You can go there yourself. You don't need to die to do it. You can do it in your sleep at night or in meditation. Strap your seat belts in because it will blow your mind."
Out of the 10 people - I believe seven people came back to me and told me about their own 'out of body' experiences and confirmed - it blew their 'egoic' point of view away.

I was in meditation and felt a great vibration going up and down my body. I felt like the "I" of me was up in the top if my head....like a pulse going up and down. "I" finally went out of my head and as I felt myself go I mentally said Neptune.
Many people describe the departure point in various ways. One of the most common is 'the top of the head.' Coming back feels like being pouring into a 'funnel through the top of the head. Like a liquid that comes back into solid matter again.
Tis a mystery......Was I out of body or was I somewhere in my own mind??
When I had my childhood NDE's - I had so many of them due to loss of vital signs. So - it became common place to me. I have spoken with many NDE'ers directly. They don't like to hear this. As a child - it was just something I understood. When your still connected to the 'silver cord' - there is a mental process still going on. There is a possibility of creating an 'illusion' and in that illusion - it is sort of a product of mental imagination. It will seem as real as real can be - but it is just a powerful 'mind trip.'
I called it 'day dreaming out side of my head.' I knew it wasn't really real because I wasn't fully merged back into the light. As an example. I could (as a spirit) take a trip to Disneyland theme park in California and be there invisible as a spirit. If I didn't like what I was experiencing (because I couldn't participate in that physical reality) I could create my own theme park and make myself the star attraction and have all the people and the 'cartoon' characters treat me like a star. My physical body would be laying in a bed with a 'flat-line' but my spirit would be outside still utilizing imagination and using the illusion of this realm to create my own reality.
If I wanted to create my own 'North Pole' - I could create a Santa Clause who showered me with every imaginable gift and toy a child could want.
Once my spirit merged back into the light or - stepped to the edge of this realm of reality - and the 'realm of truth' - my spirit would be able to tell that what I had created prior to that moment was a part of my own spiritual imagination working in combo with my mental imagination. Of course - my family could never tell when I was actually referencing something that was a 'spiritual reality' or 'imaginary' and they lumped all of it together as a product of a child's over active imagination.
From your description, I feel you had a profound meditative moment and probably did temporarily slip past the normal 'egoic' point of view. As far as the reality of what you experienced - it was real to you and served a purpose for your own study of the metaphysical subject of astrology. No one can take away from the reality that experience holds for you. What purpose that 'moment' had for you in mind - is something only you can answer.
My humble take on it - anyway.
