from which to examine  other symbols and sequences in
the dream.  I  do  not say airplanes in dream mean ideals;
I do say that my association of planes to ideals provides
one  possible  entry   into  the  dream.   From  this  entry
point,  other elements  in  the dream may or may not fall
into  place.   If   my   approach   leads  to  a  sequence  of
associations  that  gives  meaning  to  the other elements
of the dream, then  I  may have  a  helpful  and applicable
approach to the dream.  However,  it may be tempting, if
the  associations  begin  to  fit,   for  me  to  assume  too
quickly  that  the  interpretations at which  I  have arrived
are correct.
      Throughout  the  ages  of  man  up  to the present day,
there  have  been  attempts  to  categorize  men  and their
characteristics  in  terms  of  various typologies.  One of
the  earliest  of  these  was   to  classify  personalities  in
terms  of  their  similarities  to  the  qualities of the four
elements:   earth,   water,   fire,   and   air.  Although  this
seems  overly  simplified,   we   should  not  too  quickly
discount    the    possible    usefulness   of   this   ancient
approach.   Other  typologies  have  found  that  the  body
type  accurately  reflects  personality characteristics. An
example  of  such an approach is Sheldon's classification
of  physique types into  ectomorphic,  mesomorphic and
endomorphic,   each   of   which   demonstrates   distinct
personality   differences.   The   Hindus   speak  of  three
types  of  personality:   the  tamasic,   a  gluttonous  type;
the  rajastic  type,  a fiery personality;  and the sattvic, or
sanguine  personality.  The  twelve zodiacal sun signs are
also a form of typology.
      Carl Jung  worked  with a typology of four functions:
thinking,   feeling,   sensing   and   intuiting.    The   most
sophisticated  approaches  to  this  and  other typologies
have revealed  that  an  individual possesses a mixture of
different proportions  of  the  qualities  of each category
of a typology.
      If a typology can be seen as a hypothesis for entering
the dream,  rather than  a  system which  defines symbols
with  fixed  meanings,  then  the  use  of  it  may  be  very
fruitful.
      In  giving  a  possible interpretation of the Revelation
of  John,   the  Edgar  Cayce  readings   suggest   a   most
