Hi, Geno,

I, personally, have never met a person who is consciously projecting in the astral, but I've met deceased people and other beings.

Just as we exist here, our psyche also exists in the astral and higher dimensions, so as we can meet people here, we can also meet people in the astral. The thing is that being another dimension we have to use methods according to its own laws and mechanics.

hope this helps a bit.
good luck!
