Hi Mig, I have translated into Chinese, and there’s also PINYIN for your reference.
1 Do you believe in haunted houses?
你相信（世界上）有鬼屋吗？ni3 xiang1 xin4 (shi4 jie4 shang4) you3 gui3 wu1 ma ?
My opinion: I wish there’s not.. since I’m very scared about all the horrible things.
2. If you were a ghost, who would you haunt?
如果你是一个鬼，你会缠着谁？ru2 guo3 ni3 shi4 yi2 ge4 gui4, ni3 hui4 chan2 zhe shui2
My opinion: If I am a ghost, I wish to spend my every days and nights with my love. I have read an article from a girl, not to haunt him, but to accompany and focus my heart on him. I think this is the most romantic thing I could ever imagine.
3. What are ghosts? Why do they haunt us?
什么是鬼？ 它们为什么缠着我们？shen2 me shi4 gui3? Ta1 men2 wei4 shen2 me chan2 zhe wo3 men2 ?
My opinion: I don’t know actually, maybe due to something uncompleted when somebody was alive, he/she decided to be a ghost to have more time to solve.
4. What ghost movies have you seen?
你曾经看过哪些鬼片？ni3 ceng2 jing1 kan4 guo4 na3 xie1 gui3 pian1?
My opinion: The only one I seen ,is also one of the most popular movies , a Japanese movie called 午夜凶铃Rings. I saw it with my roommates in the middle night, that was not as horrible as I imagine.
5. Do people in your country generally believe in ghosts?
在你的国家里的人们大都相信鬼（的存在）吗？zai4 ni3 de guo2 jia1 li3 de ren2 men da4 dou1 xiang1 xin4 gui3 ma ?
My opinion: I don’t think so, I guess people in foreign countries maybe believe in the existence of ghost, especially in Thailand and Japan, according to some ghost movies.
