Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day.

　　【析句】Most people seem to have more bad dreams early in the night 是句子的主干，后面跟了两个现在分词结构progressing

　　toward和suggesting that ，都是作伴随状语，但是第一个现在分词结构的逻辑主语是most people，而第二个的逻辑主语是

　　suggesting 前面的所有句子成分。另外，在suggesting 的宾语从句中，过去分词结构generated during the day 作后置定语，修饰前面的

　　feelings。

　　答案：

　　多数人似乎在入睡初期做更多不好的梦，而在快睡醒前会逐渐做开心一些的梦，这说明人们会在梦里排解白天的负面情绪。
