can think of lucid dreaming as being conscious while dreaming.
If, by chance, during a dream it suddenly dawns on you
that you are dreaming, then you have experienced a lucid
dream, regardless of whether you have been able to attain
control of your dream. Lucid dreaming is usually induced
by some sort of cue—something that indicates to the person
that what he or she is experiencing is a dream, and not
reality. Cues, however, are not necessary for becoming
lucid: sometimes people spontaneously become lucid without
noticing anything strange or typical of dreams.
Lucid dreaming is a very simple concept but for most it
will take patience and determination to achieve. Many
people seem ignorant of the distinction between having
a lucid dream, and controlling a dream. Being able to
freely control one’s dream does not directly follow becoming
lucid: one can have a lucid dream without any control
whatsoever. Controlling your dream is simply proceeding
to the next level, by attempting to exert your will upon
Lucid dreamers regularly describe their dreams as exciting,
colourful, and fantastic. Many compare it to a spiritual
experience and say that it changed their lives or their
perception of the world. Some have even reported lucid
dreams that take on a hyperreality, seemingly "more real
than real", where all the elements of reality are amplified.
Lucid dreams are prodigiously more memorable than other
kinds of dreaming, even nightmares, which may be why they
are often prescribed as a means of ridding one's self
of troubling dreams.
Lucid Dreaming usually takes place in REM (Rapid Eye Movement)
sleep. There are five stages of sleep. Stage 1 being the
one you first enter, then followed by stage 2, 3 and 4.
As you descend into deeper sleep your brain frequency
slows down. In stage 4 can it be slower than one cycle
per second (delta sleep). After some time spent in stage
4, about 25 minutes, you return to stage 3 and 2, then
straight into REM sleep. About 90 minutes has passed now
since you started sleeping. 5-10 minutes is spent in this
stage before you go all the way down to stage 4 again
(also called non-REM sleep). When approximately 90 minutes
have again passed, another REM-period start. This time
the REM sleep lasts longer. And as time progresses less
time in non-REM sleep is needed and more time is spent
in REM sleep. After 4-5 hours you don't go lower than
stage 2. Vivid dreaming takes place in REM sleep, so the
more you sleep, the more time is spent in REM and the
more likely it is that you may have a Lucid Dream.
