The haunted room

"That was the year of 1999. I was visiting Mumbai, accompanied by my parents. There we booked a hotel room, it was pretty, facing the sea. But our trip would turn into a nightmare, very soon. We noticed that hotel manager hesitated for a while to handover the key of that room to us. The whole day was spent on the beach, under the sun. By the time we reached our hotel after shopping, it was already 10 pm. After returning I entered the bathroom and while standing in front of the mirror, I saw an apparition moving very fast from one side to another. I turned around, it was gone. I thought that was a mistake, so I didn't bother much.
That night my dad's scream woke us up. We saw him shivering with fear. We asked him very eagerly what happened. A horrible looking woman was trying to throttle him and asking him in angry voice 'Tell me, where is my husband? Otherwise I'll kill you'. We assured my father that it was just dream.
Later, me and my mother were discussing about that mysterious incident, when suddenly my father got into a fit of rage and tried to strangle both of us. We'll never be able to forget that moment. My father's voice turned into female voice and his face was just pale. He was crying - 'Tell me, tell me, where is my husband? He had killed me here, I want justice. Yes, I want justice. Tell me, where is my husband?' We were shouting and tried to escape from him. At that moment the hotel boys and manager came and held him down.
As we came out of the room, my father also became normal. Later, the hotel manager told us that five months ago a couple had booked that room. Next morning the woman was found dead, and her husband went missing."
