Since ancient times the belief that dreams are either warnings
or prophecies has been very common. This idea has been supported mainly
by oral tradition and some books like the Artemidorus Oneirocritica
written about 140 AD, but causing great impact right up to XIX
In more recent times, the concept of dreams telling the future has been
greatly suppressed. Partly, this has occurred under the influence of
Christian church, which has censured any kind of non-biblical prophecy.
On the other hand, conservative scientific thinking has also rejected
prophetic or precognitive dreams, probably due to the lack of
sufficiently strong proofs for their existence or a scientific
hypothesis to explain them. Thus, dreams which in the past could easily
be labeled 'precognitive', now are often thought of as mere
coincidences or stories invented by people wishing to attract more
Sigmund Freud, himself, founder of a new era in dream analysis, knew
about the existence of such dreams, but avoided speaking about them,
and explained most dreams as messages from the subconscious mind
resulting from sexual desire and traumatic experiences.
Currently, most dream scientists seam to believe that dreams express
mainly emotional states (e. g. fear, panic, anxiety, desire) and
primary instincts and most investigation is dedicated to elucidate
brain mechanisms originating dreams as a consequence of emotions and
Thus, there are hardly any studies on precognitive dreaming. However,
one name, which is worth a mention, is J. W. Dunne, who suggested that
the probability that precognitive dreams are mere coincidences with
reality is negligible and that they must be a result of time
Another important dream scientist of our times, Cencillo, expresses a
similar idea and adds that there must be a reasonable explanation in
modern physics, adducing the basic conclusion of relativistic theory
that time and space are interrelated and can be curved. He also argues
that human brain processes simultaneously past, present and future
events to represent them in a symbolic fused form as dreams intended to
alert or make us conscious about things otherwise difficult to
It should be pointed out that there seems to be certain trend of
revival of the interest in precognitive dreams. This trend is greatly
enhanced by the extraordinary features of Internet, such as web forums,
articles online, chat, galleries, etc. Based on dream communications
made in web chat and forums, Wilkerson reported that a large number of
people had precognitive dreams about the 11-s terrorist attack.
Many people question the usefulness of precognitive dream
interpretation although actually they do not reject the proper
existence of such dreams. A common argument is that what is going to
happen will happen and future cannot be changed. Nobody knows for sure
if this is true or false, but what is sure is that there are dreams
that warn or prepare us for the future rather than tell it and it can
be really useful to understand their messages. Such dreams can have as
a subject almost anything, for example, illnesses, death, political
events, financial acquisitions or losses, job changes or problems,
making or losing friends or dates, frustration or satisfaction of any
In addition to the personal satisfaction one may get from being better
prepared for the future, studying the phenomenon of precognitive
dreaming may have other positive consequences on a more global level,
such as finding the answers to some fundamental questions about our
universe and ourselves.
Creating web forums specialized in precognitive dream analysis could be the perfect way to promote and perform such studies.
