A mind machine (aka brain machine, in some countries[which?] called a psychowalkman[citation needed]) uses pulsing rhythmic sound and/or flashing light to alter the brainwave frequency of the user. Mind machines are said to induce deep states of relaxation, concentration, and in some cases altered states of consciousness[citation needed] that have been compared to those obtained from meditation and shamanic exploration.[citation needed]
The process applied by these machines is also known as brainwave synchronisation or entrainment.
Mind machines typically consist of a control unit, a pair of headphones and/or strobe light goggles. The unit controls the sessions and drives the LEDs in the goggles. Professionally, they are usually referred to as Auditory Visual Stimulation Devices (AVS devices)[citation needed].
Sessions will typically aim at directing the average brainwave frequency from a high level to a lower level by ramping down in several sequences[citation needed]. Target frequencies typically correspond to delta (1-3 hertz), theta (4–7 Hz), alpha (8–12 Hz) or beta brain waves (13–40 Hz), and can be adjusted by the user based on the desired effects[citation needed].
Gotta kill the demon
That brings evil to my world
Will erase the bad things
And the memories that keep haunting in my mind
I will raise the fever
Drive you crazy till it hurts
Gonna bring you nightmares turn your day
Into the darkest of all nights
Bad or good
I'm under surveillance
Bad or good
I rule the show, won't let you go
I'm your mind machine
I take control, affect your soul
I'm your mind machine
I'm still believing
That my feelings bring you down
You can't control the good
And positive emotions from my heart
I will make you shiver
When you hear a killing sound
I will convince you so you'll see
I was your master from the start
Bad or good
I'm under surveillance
Bad or good
I rule the show, won't let you go
I'm your mind machine
I take control, affect your soul
I'm your mind machine
Bad or good
I'm under surveillance
Bad or good
I rule the show, won't let you go
I'm your mind machine
I take control, affect your soul
I'm your mind machine
I rule the show, won't let you go
I'm your mind machine
I take control, affect your soul
I saw you for the first time yesterday
You looked at me but somethin' wasn't right
A face I thought I'd come to know by heart
Now hidden by a mask with no reveal
Just when I thought I knew you
I can feel no pulse inside your mind-machine
I can feel no pulse...you stripped my senses clean
I can feel no pulse...there's just your mind-machine
You say that you got feelin's just like me
You prove it as you throw me out the door
I'm reelin' from your sensitivity
Is this the shape of better things to come
I'm frightened for the future
I can feel no pulse inside your mind-machine
I can feel no pulse...you stripped my senses clean
I can feel no pulse...inside your mind-machine
I can feel no pulse...you broke my mind-machine
Inside your world it's cold and blue as ice
Where no one speaks and no one need reply
To questions that I've asked a thousand times
No answer to the riddles that you keep
It must be hard to be you
I can feel no pulse inside your mind-machine
I can feel no pulse...you stripped my senses clean
I can feel no pulse...inside your mind-machine
Soaring through the clouds together
We can travel on forever
Through the sky you and I
Back to earth again
And we're in a mind machine
I see the things I want to see
I can be all the things I want to be
Is it real or just a dream
Come fly with me, come ride with me
We're in a mind machine
Together we can touch the sky
You and I, we're in a mind machine
Come on and fly with me, come ride with me
We're in a mind machine
Take my hand you'll understand
The wonders I have seen in my mind machine
Onward through the atmosphere
Everything is crystal clear
Finally we can see, the world as it should be
And we're in a mind machine
I see the things I want to see
I can be all the things I want to be
Is it real or just a dream
Come on and fly with me
Come touch the sky
Come fly with me, come ride with me
We're in my mind machine
Take my hand you'll understand
The wonders I have seen in my mind machine
The wonders I have seen
In my mind machine
Come fly with me
All free will is gone
Automatic knowledge
Humans lead in leashes
Silent, untrue
All are subjects to
Automated liars
Broadcast feelings through
Machines that makes you
Wither away
Death of the soul
Indoctrinated in false grace
Bio-machinery
Mind and machinery
Fear now fuels the system
Bio-machinery
Target is the world
Structuring the madness
Terminating ancient
Concepts of truth
Power structure comes
Silent weapons fired
Quiet wars in minds
The damage is done
Wither away
Death of the soul
Indoctrinated in false grace
Bio-machinery
Mind and machinery
Fear now fuels the system
Bio-machinery
Solo: P. Nilsson
All hope that died must rise anew
By facing the passage of time
All that we've known was bound to drown
Before we could wake
Bio-machinery
Mind and machinery
Fear now fuels the system
