Two possible answers

[essam nasr]

I don't like people laugh at me = I don't like being laughed at (by people.)
I don't like people who are laughed at (by others.)= I don't like people laughed at.

أعتقد في اجابتين صحيحتين

being laughed ---&--- people laughed

من من السادة المدرسين يوافقني الرأي؟؟؟
