     History is full of cases where dreams have been a pathway to creativity and discovery.A striking

example is provided by Dr.Otto Loewi, a pharmacologist and winner of a Nobel Prize.Loewi had

spent years studying the chemical transmission of nerve impulses (脉搏). A tremendous breakthrough

in his research came when he dreamed of an experiment three nights in a row.The first two nights he

woke up and wrote down the experiment quickly and untidily on a pad.But the next morning, he

couldn't tell what the notes meant.On the third night, he got up after having the dream.This time, instead

of making notes he went straight to his laboratory and performed the crucial experiment.Loewi later said

that if the experiment had occurred to him while awake he would have rejected it.

     Loewi's experiment gives some insight into using dreams to produce creative solutions.Inhibitions (拘谨) are reduced during dreaming, which may be especially useful in solving problems that require a fresh

point of view.

      Being able to take advantage of dreams for problem solving is improved if you "set" yourself before

retiring.Before you go to bed, try to think intently about a problem you wish to solve.Steep yourself in (潜心于) the problem by stating it clearly and reviewing all relevant information.Then use the suggestions

listed in the previous section to catch your dreams.Although this method is not guaranteed to produce a

novel solution or a new insight, it is certain to be an adventure.About half of a group of college students

using the method for a week recalled a dream that helped them solve a personal problem.
