3 Simple Questions Options

- Is it possible obtain omniscience with AP (Astral Projection)?

-Is it possible bring physical objects back with you with an AP (flowers, coins, clocks, whatever)?

-Using energy of astral plane, is it possible a physical shapeshift?

Thanks in advance.

During OoBEs you can have experiences in which you are omniscient, like in a Satori or Samhadi, but all of that knowledge won't fit into your human brain. You might know that you knew things then that you don't know now, but not the specifics.

In answer to your second question, I can only speak to my own experience. I have only brought back strange energies or some sorts of information, nothing material.

Physical shapeshifting seems unlikely to me. But others may have different experiences.
