But the Astral can be a wild and crazy place, so you might go to the right place at the wrong time (when the person is not there, even though they are there at the present time you might have gone to the past or a possible future), or the other person might have such a great belief in their privacy that you get misdirected.
Once, I projected into a room while my roommate was at the computer, and I tried to peer over her shoulder to see what she was surfing, and what I can only guess was her AURA pushed me back--through the wall and into some level of the Astral that was nothing like the physical world anymore.
Grounding and centering, but that means so many things to different people that it can be difficult to explain. It's not necessarily the sight, even... it's the "weather" I guess you could call it. The astral gets some strong winds.
Can you see a person that is astral projecting or spying on you??. e.g. Like appear in front of you,then vanish into thin air?!!.And can I have a conversation with them without pysical contact!?!.
Oddly enough, I've never been able to do that. My ex-mentor in psychism said that he was doing that to check up on me, and he did give some information that made it out that he was somewhat checking up on me, but I never saw him (and it actually didn't sound like he saw me , so maybe that was more divination than astral projection, but I think that's sort of like splitting hairs with this stuff.)
The theory that I've gone with is that the Astral plane is where magic moves and ghosts do their haunting, and astral projectors travel, of course--so, I want to say theoretically yes.
Clearer vision is pretty much just about practice. The more you do it, the more natural the entire experience. You relax and notice more detail. That enables you to sort of flip a mental switch (figuratively) and see at the level you want to as well as be able to discern what you're seeing. Most people without much experience see everything at the same time and notice no separation which makes it seem extremely chaotic.
But don't forget, magick is on that level of existence as well which is why willpower matters. If an individual wills strongly and consciously for no one to see them, whether they practice magick or not, this will matter. This is also why some things are just plainly erroneous. It's not as simple as just physical, but equally mental and emotional forms.
But you don't need to fully project to do this. You can achieve it just as well through simple meditation. It's about letting go of physical restraints and allowing your consciousness to roam. Many philosophies believe that everything is connected. When you practice meditation you can teach yourself to travel this connection.
