There
is an endless supply of stories about sleepwalkers (梦游者).
Persons have been said to climb on roofs, solve mathematical problems, write
music, walk through windows, and do murder in their sleep.
In
Revere, Massachusetts,
a hundred policemen searched for a lost boy who left his home in his sleep and
woke up five hours later on a strange sofa in a strange living room, with no
idea how he had got there.
At
the University of Iowa, a student was reported to have the habit of
getting up in the middle of the night and walking three quarters of a mile to
the Iowa River. He would take a swim and then
go back to his room to bed.
An
expert on sleep in America claims(声称)that
he has never seen a sleepwalker. He is said to know more about sleep than any
other man alive, and during the last thirty-five years he has lost a lot of
sleep watching people sleep. He says, “Of course, I know that there are
sleepwalkers because I have read about them in the newspapers. But none of my
sleepers ever walked, and if I were to advertise for sleepwalkers for an
experiment, I doubt whether I could get many takers. ”
Sleepwalking,
however, is a scientific reality. It is one of those strange things that
sometimes look quite like the fantastic(怪诞的).
Doctors say that sleepwalking is much more common than is generally supposed.
Many sleepwalkers do not try to find help and are never recorded.
