THE SCIENCE
BEHIND
SLEEPING AND
DREAMING
Sleep is important
Even if it is a basic need,
usually due to our fast and
extreme rhythm of life, we
don´t give enough importance
to sleep.

Why we need dreams?
Dreams have these
benefits:
representing
unconscious desires
and wishes
consolidating and
processing
information gathered
during the day
interpreting random
signals from the
brain and body
during sleep
working as a form of
psychotherapy
ANATOMY OF
DEEP SLEEP
Sleeping
a complex process
Chemistry of
sleep
GABA, acetylcholine, orexin,
and serotonin are
Neurotransmitters.
5 phases of sleep
Within a minute after falling
asleep, notable changes start to
affect both the brain and body.
THERE ARE FIVE PHASES OF SLEEP IN
A SLEEP CYCLE:
Stage 1: Light sleep, slow eye movement, and reduced muscle activity.
Stage 2: Eye movement stops and brain waves become slower, with occasional bursts of rapid waves
called sleep spindles.
Stage 3: Extremely slow brain waves called delta waves begin to appear, interspersed with smaller,
faster waves.
Stage 4: The brain produces delta waves almost exclusively.
Stage 5: This stage is known as rapid eye movement (REM). Breathing becomes more rapid, irregular,
and shallow, eyes jerk rapidly in various directions, and limb muscles become temporarily paralyzed.
Heart rate increases, blood pressure rises
Over the course of one night, you actually
progress through multiple sleep cycles, each
of which lasts between 70 and 120 minutes
REM STAGE
What is REM?
• The brain is more active during REM sleep,
• Studies said that only if you get enough sleep to go in the REM part,
you can have a vivid dream.
• REM is crucial because It activates the part of the brain that aids in
learning and is linked to an increase in protein production.
• Rem dreaming can help you learn and develop long-term memories
DREAMS
There is no cognitive state that has been as extensively
studied and yet as frequently misunderstood as dreaming.
Reports of dreams tend to be full of emotional and vivid
experiences that contain themes, concerns, dream figures,
and objects that correspond closely to waking life.
DREAMS DON´T PREDICT THE FUTURE, but elements
from the everyday re-emerge in dream-like imagery during
the transition from wakefulness to sleep (so, they can help
you to Make your desires a reality if you use it to reflect)
