You sound like you are attempting to meld the fields of metaphysics and technology... To be honest, I have no clue what you are even talking about. To be able to manipulate the physical world in even the slightest bit while in the metaphysical plain would be nothing short of amazing. But somehow manipulating data in it, then sending it to a computer? I'm quite certain that no human in existence right now could perform such a feat. Frankly, I don't even understand how you could come to attempt to meld these two things together? No technology on Earth can access the metaphysical realms in any way, shape, or form. Now in theory, one might be able to access their computer for the metaphysical realm and transfer data through it somehow to a digital device via a highly complex process. But that is a very, very loose hypothesis, and one that has quite the margin to prove false. And even if it was true in theory somehow, it would require a level of intelligence, skill, and sheer ability that is not possible by any human being to ever live, and likely will not be possible by human beings for the rest of eternity, unless some divine being bestows upon mankind immense knowledge and power. And let's be honest. The chances of that happening are, as it seems right now, next to zero.
Now perhaps what your are describing is some roundabout description of something much simpler. But if what you're describing is to be taken literally, then I can say beyond a shadow of doubt that what you are describing is impossible to such a degree that I'd dare to call it absurdly impossible. To be honest, I recommend you just upgrade your internet service if possible. Perhaps that's what your dreams were trying to tell you all along.
Now on a side note, you may find knowledge in the astral plain via your encounters with other beings there, or just pure experiences (frankly, very little is definite about the metaphysical world, so it is difficult to describe in specific terms). But as for transferring information to one or more other people in the astral plain... I'm afraid the best I can offer is trying a spell while in the metaphysical plain (if even possible in that state), and hoping it works. Otherwise, I don't think anybody has really discovered much about transferring information through the metaphysical plain. I may have missed some sort of information regarding that for all I know, but this is what I can offer. As far as I'm aware, you're out of luck in both regards.
