Several years ago, my aunt ask me to live in her house for 2 weeks, because she has to go back to China for that period of time. So I stay, pick up mails and such. However, I always feel I heard some noise in the house, but I made promise, so I continue stay.
One day, my boyfriend ( who is my current husband ) visit me. When we try to hug and kiss each other upstairs while watching TV, I hear the voice of my aunt, she is talking to someone and come upstairs. I immediately push my boyfriend away. I ask my boyfriend if he hear anything, he told me he heard my uncle's voice and he's coming upstairs. Of course, we checked, there is nobody in the house.
My aunt and uncle still live in that house, don't know whether they can hear their own voice.
Above is true story of mine.
