Since the beginning of time, the mysterious nature of
dreaming has led people to believe that dreams were
messages from the other world. Dreams have been regarded
as prophetic communications which, when properly decoded,
would enable us to foretell the future. There is, however,
absolutely no scientific evidence for this theory. It is
certainly true that individuals who are concerned about a
traumatic event, such as the threat of the loss of a loved
one who is sick, will dream about that loved one more
than would otherwise be the case. If the dreamer then calls
and finds that the loved one has died, it is understandable
for him or her to assume that the dream was a premonition
of that death. But this is a mistake. It is simply a(n)
correspondence between a situation about
which one has intense concern and the occurrence of the
event that one fears.
To prove the existence of premonitory dreams, scientific
evidence must be obtained. We would need to do studies
in which individuals are sampled in terms of their dream
life and judges are asked to make correspondences between
these dream events and events that occurred in real life. A
problem that arises here is that individuals who believe in
premonitory dreams may give one or two striking examples
of ¡®hits,¡¯ but they never tell you how many of their
premonitory dreams ¡®missed.¡¯ To do a scientific study of
dream prophecy, we would need to establish some base of
how commonly correspondences occur between
dream and waking reality. Until we have that evidence,
it is better to believe that the assumption is false.
