The ghost shushed her!

Is it possible to hear ghosts in other rooms? I think I heard mine last night. I woke up in the middle of the night to Kyra crying. It was an instant reaction. Then I heard someone shush her. My immediate thought was that I must have slept through something that happened earlier in the night and Jeff was already in there with her. But he wasn't. He was next to me. And she stopped crying. I'm not really sure what to make of it. Jeff thinks she made the sound herself. I know she didn't. I just know. So the next morning I told her I heard her crying and asked her if she had a bad dream. She said she did, something about monsters and ghosts trying to take her animals. Okay, I'm not getting anything good here. I know what I heard. I know I heard a shush. I could even describe it to you. It wasn't a long, softly drawn out shhhhhhhh. It was a shush. Concise and deliberate. I don't know if I should be concerned. Things go missing around here, then we eventually find them. But I'm frequently distracted and don't always put things where they belong. I'm more aware of it now so it seems to happen a lot. I haven't "seen" the ghost, but I think about seeing it (her) every single day. I'm so hyper-aware that I'm sure I won't see anything. But last night was one of those "caught off guard" moments. And that's all I'm saying.
