From
dreams,
in
sleep
or
swoon,
of
a
character
difficult
to
believe
in
we
pass
by
way
of
"hallucinations"
to
ghosts.
Everybody
is
ready
to
admit
that
dreams
do
really
occur,
because
almost
everybody
has
dreamed.
But
everybody
is
not
so
ready
to
admit
that
sane
and
sensible
men
and
women
can
have
hallucinations,
just
because
everybody
has
not
been
hallucinated.
On
this
point
Mr.
Francis
Galton,
in
his
Inquiries
into
Human
Faculty
(1833),
is
very
instructive.
Mr.
Galton
drew
up
a
short
catechism,
asking
people
how
clearly
or
how
dimly
they
saw
things
"in
their
mind's
eye".
"Think
of
your
breakfast-table,"
he
said;
"is
your
mental
picture
of
it
as
clearly
illuminated
and
as
complete
as
your
actual
view
of
the
scene?"
Mr.
Galton
began
by
questioning
friends
in
the
scientific
world,
F.R.S.'s
and
other
savants.
"The
earliest
results
of
my
inquiry
amazed
me.
.
.
.
The
great
majority
of
the
men
of
science
to
whom
I
first
applied,
protested
that
mental
imagery
was
unknown
to
them,
and
they
looked
on
me
as
fanciful
and
fantastic
in
supposing
that
the
words
'mental
imagery'
really
expressed
what
I
believed
everybody
supposed
them
to
mean."
One
gentleman
wrote:
"It
is
only
by
a
figure
of
speech
that
I
can
describe
my
recollection
of
a
scene
as
a
'mental
image'
which
I
can
'see'
with
'my
mind's
eye'.
I
do
not
see
it,"
so
he
seems
to
have
supposed
that
nobody
else
did.
