Face Behind the Curtains

This happened last night on 3/24/07. It was about 1:30 a.m. My cousin and I couldn't go to sleep because of the noises and things we saw. My uncle and aunt were sleeping. We were the only ones awake and we were alone in the living room. My older cousin was working. My younger cousin and I were telling stories. That's when I heard a whistling by the bathroom. My cousin then told me she wanted to go to the bathroom and when I told her what I heard, she didn't want to go. Then my older cousin came and started eating in the living room where we were. My uncle came out of his room and told us about a dream he had. I wasn't paying much attention because I was being distracted by something I saw behind the curtain. I was looking closely and it looked like an old woman's face. Then the face disappeared but I still saw a bump behind the curtain. I went to check with fear. I opened it but I didn't see anything. I didn't tell anyone until the next day to not scare them. I still never found out what was actually behind the mysterious curtains.
