I finally realized what this is and what I did wrong so far. I mean I always suspected it because it didn't make sense otherwise but now I experienced it. Now I know why "vampires" can't "astral project". As I was sleeping and wandered off with my mind as usual I noticed that my particle is not "pushing" out the energy. I had a minor panic attack Then realized why this whole thing didn't work so far because I "moved around" the connection point of the particle the whole time. I literally connected it to every idea I had to see how they "feel" for divination... This is why I got nowhere in the past 2 years. This is why "resetting" it helped. Now I understand this whole tunneling that took place. And why I could "breathe in and out" the shadow realm. The shadow realm wasn't infinite. As I took the energy out I had to put it back because it wasn't overwhelming. When I reached the "red" realm it was pouring in. It's infinite or extremely abundant quality was obvious. This is why we need to "lock" into that realm. This is why we can't move around as "freely". The particle has to stay connected. If we move around the part where the particle is we lose the power connection. This is why we need to unify the astral and the physical properly. So the energy can flow into the physical body. And as the physical starts to "dry out" (hence that whole "vampires has the signature of a dried up river") your body will work off from nothing but this energy. And as "you are what you eat". Your body gets closer to this "red" realm. This is why vampires can turn into fog and other sillyness and go full astral in the end. And about those things we develop as we get "older". The buckler shield, the pocket dimension, physical teleportation. We learn to utilize this "particle" then "full circle" into proper wormholes/portals. This is why the buckler shield works "as invisibility" it projects the image from one side to the other while you are in-between. The pocket dimension is just a place outside time and space. And the reason why physical teleportation needs the same temperature/energy at the connection points because otherwise the big energy fluctuations would mess with the places. We are not vampires not in the mainstream way for sure. We are not "sucking" out the energy. The energy is so abundant if you can make the connection point properly it pours in without effort.

A "little girl" at some vampire party I accidentally wandered in then I walked out because mingling with strangers is not my style was teaching me things. We started off with time manipulation and because I had some previously developed skill with that I could do that with ease. Then she said:
>You are good at this. Now I'm gonna teach you how to teleport!
Then she teleported away. I was there thinking that does she want to me to teleport after her so she can teach me teleporting? It was not something I would call weird or unexpected so I tried to "teleport". The thing I did was I got lost in some "foggy" "wall" and lost the connection to the place. Then with my realization I went back to the very place the little girl stood when teleporting away... It had a wormhole to some mountain location... It was just not visible from afar...
We are not vampires. We are the lords of space and "time". Who happen to connect to some realm of "infinite" or overabundant energy. This is not just a shortcut. This is the mastering of shortcuts.
