dream of和dream about有什么区别

各位老师好，请教dream of和dream about有什么区别。

1、She tried to turn her dream of running her own business into reality.

2、He had a dream about Claire.

  请问例句1中of后面的内容是否做dream的后置定语？例句2 dream about是个短语，Claire是宾语？

        例句1中的 of running her own business 是dream的后置定语，例句2中的 dream about是个短语，Claire是宾语。
