VR analogy for Turiya

In Vedanta,
There are the following different states of consciousness:
# Turiya
# Deep sleep = Turiya + Deep sleep
# Dreaming = Turiya + Deep sleep + Dreaming
# Waking = Turiya + Deep sleep + Dreaming + Waking

Turiya is not really a state,
But it is the transcendent reality,
That underlies all the 3 states,
Of waking, dreaming, sleeping.

A great way to experientially imagine this,
Is to take the analogy of a VR headset.
You are Turiya.
You first wear the VR headset ‘switched off’ on your head first = Deep sleep
Say the VR headset cycles through these 3 states of:
# Being switched off = Deep sleep
# Movie mode = Dream
# ‘First person’ avatar game mode = Waking
Let’s imagine there are 2 screens on the VR:
# The screen closer to your eye is the movie screen.
# The screen farther away from your eye is the game screen.

The 2 can play simultaneously also, but generally,
When the game screen is switched on,
The movie screen turns translucent,
And serves as a sort of AR (augmented reality) for the game screen.

Imagine you forgot you were wearing this headset,
And got immersed into the game screen appearance,
Then you will believe the game world shown on it is the ground reality.
Supposing you snapped out of the trance,
And realized you were wearing the headset,
This real you that woke up to this is ‘Turiya’.
The VR headset still cycles between being switched off, movie mode, and game mode.
However now the real you is awake behind all of these states.

Imagine trying to convince another avatar in the game mode,
That he is actually another person like you wearing the headset.
How would you go about it?
Whatever he points to in that VR game world,
And even his avatar body, would have nothing to do with what you are trying to point at.

Similarly the other implication of this analogy would be that:
If you went to deep sleep in the game mode for the other players,
It means your headset is in its turned off state.
The real you wearing the headset is still awake.
However, since your headset is switched off, you would receive no information from the VR game world.
Other players would find you motionless/asleep/dead.
And even if they waved at you from within the game,
You would not receive that.
But however the real you, is still awake,
Just observing the blankness of the switched off screen.
This real you that is transcendent of the VR headset and its simulated worlds = Turiya.

The body is like a million pressure sensitive key piano

brainregions

If there are a million chemicals/neurotransmitters in the body,
Then who/what is the player of this hardware?
Is it prana? And the prana is controlled by the mind?
The mind is controlled from the intellect/knowing?
And then there is the blankness of deep sleep?
(using terms from the vedantic model)

GROSS:
So there is a physical form in the physical world.
SUBTLE:
There is a pranic form in the “pranic world/astral world”.
There is a mental form in the “mental world”.
There is a intellect form in the “intellect world”.
CAUSAL:
There is deep sleep dormancy of the seed, “causal world”.

So influences are transmitted from:
Deep sleep -> Intellect -> Mind -> Prana -> Physical body.
Through the 5 koshas (vedantic term).
So life force seems to be progressively cut off,
Until only one personality finally manifests in/as experience.

There are also various thresholds for activation in the brain areas.
Levels of activation: Say from RED/YELLOW(highest) to GREEN(moderate) to BLUE/VIOLET(lowest)
Like for instance, in PTSD, tiny cues may cause a lot of unpleasant areas to activate.
And if you repress something, then only a very high stimulus will make that portion activate.
