Below is my diagram for how I experience the Lower Astral energies - I feel, from my experience, that they're very close to the Earth's surface and beneath the Earth's surface.
It's also my view that the Lower Astral energies are comprised of many things:
Earthbound souls who died tragically (or even not so tragically) and are 'lost' (hence paranormal activity, what some might call 'demonic' activity). Some of these souls might have been raised in a very strict religious upbringing and are afraid to 'cross over' - so they have/carry a lot of fear with them.
Residual Energies - from Wars, Murders, Sudden Deaths (such as accidents)
Energy from Pollution
"Black Earth" Energies and Entities - this is the stuff that exists underground
Fears (religious/spiritual and otherwise - not all fear is bad...there is survival fear which helps one escape danger - but there are a lot of uneccessary fears), Terrors, Shock and Trauma
'Shadow' Energies (shadow self energy)
Hatred (as opposed to Anger)
Energies such as hating this planet, that it sucks, that it's a jail/prison only feeds this mass of lower astral energy and does nothing for the planet nor the one doing the hating of it (see the quote about hating and poison).
So as you can see, a lot of this Lower Astral is mainly a conglomeration of 'stuck' and 'uncleared' energy composed of a multitude of things - a 'mass of stuff'. This is the stuff that makes this planet 'icky'. It's not 3D itself that's 'icky' - it's all this Lower Astral 'stuff'...this 'muck'. 3D Earth could become a reflection of 6D Earth once this 'ick' is cleared away.
I have come up with an essence blend that works, at least in my location, for clearing this sort of energy. I keep it in a bottle and keep the bottle on the floor in my kitchen. I've found that when 'planting' bottles on the floor in my apartment, you can usually 'sense' where they will work best. I just walk around carrying the bottle and I will 'feel' where a 'spot' is that could use a bottle. I try to make sure the bottles are 'out of the way' for obvious reasons, and it's usually not too difficult to do this. Whether or not I am winding up putting them on actual Ley Lines remains to be seen, as I do not have dowsing rods at this time.
One need not buy all these different essences - what you can do is use photos of the items listed, and/or, write down the essence blend with the maker, and put a small glass or spice jar over the words/image. This is a quick, free, and easy way to make these essences - if you want to do it that way as a permanent thing, or something to 'hold you over' if you decide to buy one or more of the essences.
The essence blend is:

From personal experience - this essence helps to 'spread' the energies in all directions.
Comet 21P/Giacobini-Zimmer
Affirmation - I Know I Am Always Safe & Well, Basking In Divine Light & Love
Releases a person from the paradigm of fear. Some fears are reasonable and important for our continuing survival at this time. (This is in the process of changing however). But the level of fear on the planet at this time is so overwhelming that it is inhibiting too many people from truly living their lives. This essence addresses this issue as well as repelling those whose greed spurs them on to feed of others fears and in the process creates new fears.

From personal experience - this helps destroy the 'Black Earth' entities living under the surface.

A blend I use to also help keep the 'surface of the Earth/ground' clear is:
Actinolite, White Copal, White Sage, and Green Fluorite - with a piece of White Copal resin and some Sage essential oil and dried herb in the bottle. This tends to work excellently for where I'm at (which is right in one of the busier parts of the small town I live in).
