persons frequently have these comforting _dreams_ before waking, just
when they are called. They then dream that they are already up, that
they are washing, or already in school, at the office, etc., where they
ought to be at a given time. The night before an intended journey one
not infrequently dreams that one has already arrived at the destination;
before going to a play or to a party the dream not infrequently
anticipates, in impatience, as it were, the expected pleasure. At other
times the dream expresses the realization of the desire somewhat
indirectly; some connection, some sequel must be known--the first step
towards recognizing the desire. Thus, when a husband related to me the
dream of his young wife, that her monthly period had begun, I had to
bethink myself that the young wife would have expected a pregnancy if
the period had been absent. The dream is then a sign of pregnancy. Its
meaning is that it shows the wish realized that pregnancy should not
occur just yet. Under unusual and extreme circumstances, these dreams
of the infantile type become very frequent. The leader of a polar
expedition tells us, for instance, that during the wintering amid the
ice the crew, with their monotonous diet and slight rations, dreamt
regularly, like children, of fine meals, of mountains of tobacco, and of
home.

It is not uncommon that out of some long, complicated and intricate
dream one specially lucid part stands out containing unmistakably the
realization of a desire, but bound up with much unintelligible matter.
On more frequently analyzing the seemingly more transparent dreams of
adults, it is astonishing to discover that these are rarely as simple as
the dreams of children, and that they cover another meaning beyond that
of the realization of a wish.

It would certainly be a simple and convenient solution of the riddle if
