The human brain produces electrical
activity that can be measured as brain waves. An electroencephalogram (EEG)
measures brain waves in frequencies
also known as cycles per second or hertz. The table below explains four different
brain wave states and how brain waves are related to hypnosis, the conscious,
and subconscious minds.
Brain Waves |
States of
Consciousness |
Frequency |
| Beta brain waves |
Waking conscious state, alert |
14-30 Hz |
| Alpha brain waves |
Daydreaming, creative, relaxed, closed-eyed |
8-13 Hz |
| Theta brain waves |
Dreaming, hypnotic, meditative, subconscious,
athletic "in the zone" |
4-7 Hz |
| Delta brain waves |
Unconscious, asleep, deep sleep |
0.5-6 Hz |
1. When you are awake, your brain waves are operating in the beta state
of activity, that is, 14-30 hertz. Beta is the state of normal wakefulness.
In beta, you are alert and wide awake. Your conscious mind is dominant.
Beta state is where your brain waves would register during the beginning
of your hypnosis session during the interview process.
2. When you close
your eyes, become relaxed, or daydream, your brain waves are in alpha.
This is the brain wave state of heightened creativity and inspiration.
When
you engage in creative endeavors such as imagining or visualizing your
brains waves register in alpha. In alpha, your conscious mind is less
dominant
and
the subconscious
mind
is coming
to the forefront. Alpha state is where your brain waves
would register as when you go into a light trance (light hypnotic state).
The subconscious mind does not register the difference between imaginary
reality and physical reality. It simply does what it is told, shown,
or imagined until it becomes a habit. That is why hypnotic suggestions
can have powerful effects in the alpha brain wave state.
3. When you are dreaming, in deeper hypnosis, meditating, or in the zone
in sports, you are in theta. Any repetitive movement or sounds
will take you into the theta state easily. This state is where much
of your
subconscious potential lies and where the subconscious mind is totally
dominant. Theta state is where your
brain waves
would register
as your hypnotherapist takes you deeper into hypnosis where past experiences
and emotions can be accessed. In theta, many people can go into deeper
stages where hypnoanaesthesia can be experienced. Hypnoanaesthesia
occurs when clients are so deeply relaxed that surgeries can occur
with sensation but without pain. More people are using hypnoanaesthesia
as an alternative to anaesthesia during childbirth, dental procedures,
and surgeries since there is no danger of dying from hypnoanaesthesia
as there is with anaesthesia.
4. When you fall asleep and go into unconsciousness, you are in delta.
In this state of consciousness, you will not remember what you are
experiencing because
you are asleep and will eventually go into the stage of deep sleep
or total unconsciousness. Delta state is where your brain waves
would register if you fell asleep during your hypnosis session. Most
clients do not fall asleep during hypnosis because that would go against
the definition of hypnosis (hypnosis is focused attention combined with
deep relaxation). If a client falls asleep during hypnosis, s/he has
lost
focus even though
relaxation is deep. Clients may fall asleep for a brief moment or two,
but normally, they come back into a theta state where they can focus
their attention.
Your brain can be functioning in more than one brain wave state simultaneously.
For example, you can be in beta as you enter into alpha. You may be
completely awake one moment and then feel more relaxed and close your eyes
all in a few seconds. You could also be dreaming (theta) and rise up into
wakefulness (beta) and then go back into a higher frequency (theta) than
previously.
Understanding brain waves can help you connect the experience of hypnosis
with brain wave activity in your brain. Most people enter alpha and theta
states during hypnosis, and each subsequent time, they tend to go into deeper
states of hypnosis or further into theta. If you fall asleep during hypnosis,
you have gone into delta or deep sleep. You are unconscious at this point,
so suggestions cannot take hold in the subconscious mind. On the other end
of the brain wave continuum, if you remain in beta, your conscious mind is
dominant. You will have too many filters such as beliefs, values, ethics,
and past conditioning to allow suggestions to take hold. If you are
