never wonder why you dream and what they
actually mean researchers think there
are two main reasons the first being
creativity so you may have heard of
sleep stages before we all start in
these light stages of sleep then we
enter deep sleep and then finally rem
sleep or rapid eye movement and that's
where you actually experience dreams now
in deep sleep you take the experiences
of your day and consolidate those
memories but it's in rem sleep that you
start to make connections between all
the things that wouldn't have been so
obvious in your waking life that's why
people often say to sleep on your
problems because you're more likely to
wake up the next day finding interesting
connections that you never could have
made at the time now the second reason
is even more fascinating and it's a type
of emotional age so there's a stressed
chemical called nor adrenaline which
only turns off at one time whether
you're awake or asleep and that's in rem
sleep and so dreams are a chance to take
those difficult or emotionally complex
parts of your life and experience them
devoid of stress in fact in patients
with ptsd sometimes their levels of
noradrenaline are too high and that's
why this process can't function properly
so the next day even though you remember
it as an emotional experience it doesn't
feel so difficult anymore
