请问我翻译的对吗？

都不对吧...........汗

应该是I dreamt that you killed a person in the school last night.

Last night I dreamed you. you killed some one in the school.
I had a dream of you last night, you killed some one in the school.

Last night I dreamed you. 我昨晚梦见你。这是英汉词典的例句。

注意时态。

killing

Last night,I dreamed of you killing someone on campus

I dreamt that you killed someone at school last night.
注意时态~~

是对的

I dreamt about you last night,you kill a person in the school
昨晚我梦见你,你杀了一个人在学校
