NOTE: This is my understanding that seems to have been proven at least somewhat accurate, but entities have a deeper understanding of how it works as being able to easily observe the planes. From what I gather they more so view planes differently.
A common misconception in these communities much like the last one I wrote up (Energy Vampirism), is the understanding of the commonly projected to “Planes”.
I would like to clear up some misconceptions on the following planes, The Astral and the Etheric

First one we will clear up is the misuse and misconceptions of what the astral plane exactly is, this one is the most common or the word is mostly used wrong in these communities. I know everyone has their own uses for words, but I have found these definitions to be accurate enough that they shouldn’t be unknown.

The astral for a lack of a better explanation is the shared “thought plane” by every sentient entity in the universe, (Including physical people).
Everything in this plane is merely a thought that seems to be real to the onlookers, much like a dream.
The entities in this plane are usually other “real” entities projecting into it, or thought forms, some thought forms can develop into being independent entities, but normally they rely on the mind who created them to live.

The next plane that is commonly the center of many misconceptions, huge misconceptions in fact.
The etheric is a parallel physical plane that is much like this one but not covered in what people know as the “Veil”. As in energetic beings are free to move through it, as well as the physical beings on that plane are capable of using energy just as well as fully energetic beings.
This plane is commonly thought to be the land where entities “live”, but that is in fact not true, there are simply other races other than just plain humans living there.
Last common misconception is the idea that when you die you go there, or vise-versa. Rather, you don’t go to the etheric unless you are reincarnated there, normally you just become a energetic being like entities, or of course, reincarnated.
