有些人可能不知道:夢被視為是一種治療方法，一種「身，心，靈」療法之一.正如我先前提到的「夢中哭泣」 ，它就如「沮喪紓緩劑」一樣，幫助我紓緩人生的壓力.我記得在無數的夜晚夢到自己哭泣，特別是在我父親過世之後.一種很深的痛楚在我心中，久久不能揮去.我時常在白天哭泣，而晚上睡不著.當我聽到救護車的鳴聲呼嘯而過時，我也會哭泣.我知道這與我父親的死有關，因為他常到我的夢中.然後，有一天晚上，我真的很累而終于入睡，我開始作夢，又夢到自己正在哭，身體也因為哭泣而搖動起來.突然，我的淚水像海嘯般的朝我全身傾倒過來;那種要溺斃的感覺把我弄醒了，而我的全身仍在晃動How privileged we were to witness this coronation ! although the concert concluded with the joyful notes of the beach boys family and friends, i fervently believe that it was not the end, but that " one world. . of peace through music " was a momentous prelude to " ring in " a new era ; its beautiful yet powerful music will continue to echo, inspiring countless right actions by humankind until we reach the final goals of one world of peace and happiness on earth
