My daughter talks to someone in her sleep. It isn't me.

Needing to get out for a bit, I took my daughter to a diner for breakfast. We sat in the back corner, at the same table where we had been a few nights before. Taking a seat across from Amy and sliding a menu her way, she politely declined and ordered waffles. I smiled and ordered the same, making sure to request extra fruit. Our old waitress took our menus and left for the kitchen without saying a word. <br><br>"You know, I'm not crazy, don't you think that?" Amy asked. "You heard her, right?"<br><br>I took a deep breath and rubbed my face, exhausted with all that had happened. "Knock, knock," I said. <br><br>"How will I know if theres a knock?" Amy asked, remembering the old joke we had played with Rachel. When Rachel had stayed with us the first time, she insisted Amy and I knock every time we entered her room. <br><br>"Good point," I said. "Okay. It's actually a different joke. Knock, knock, Amy." <br><br>"There's a knock!" Amy said, giggling. <br><br>"Who's there?" <br><br>"I did." <br><br>"I did who?" <br><br>"I did hear the lady. I heard Rachel talking to her and the lady talking back. I'm glad we got the house, daddy. I dont think I could live in our old house again." Amy said, looking down, trying to hold back tears.<br><br>"Yes, Sweetie, I heard her too," I said, after the waitress had set our food down and left. <br><br>Amy looked up at me, a smile spreading across her face. "I'm glad we're in this together," She said.<br><br>I smiled back and reached out, brushing a lock of hair behind her ear. "We're in this together 'til the end, Kiddo," I said.<br><br>We ate the rest of our breakfast in silence, enjoying each others company after a very long night. After finishing, I asked our waitress for the check, then reached into my pocket to fish out some money. <br><br>I had just grabbed the check when Amy spoke up, as if a conversation was ongoing that I had missed. "That isn't my daddy," She said.<br><br>I looked over, expecting to see Rachel standing next to our table, but she was nowhere to be seen. I looked back at Amy, who was staring into space just above the table. "Amy, it's me. It's okay, Sweetie," I said.<br><br>"No, that isnt my daddy," She repeated. "My daddy is strong, handsome, and brave. He would never hurt me."<br><br>"Amy, its me," I repeated, tears welling up in my eyes. It hurt to here her say theres a better man in her life than me.<br><br>"I'm not talking to you," She said, looking at me. "You're not my daddy." <br><br>I looked back to the spot where she was staring, but saw nothing. "Amy, please," I said, trying to grab her hand. She jerked it away and began to stand up. <br><br>"I'm not talking to you," She repeated. "I'm talking to the lady. I'm not scared of you, lady. My daddy will always protect me."<br><br>I stood up, trying to usher Amy out in the cold, hoping it would calm her down. "Amy, please!" I said. "There's no one there! Let's go for a walk." <br><br>"I'm not talking to you," Amy said again. "I'm talking to the lady. You're not my daddy. I'm not scared of you."<br><br>I reached out and grabbed her hand, pulling her through the diner. "Amy, stop," I said. "You're starting to scare me."<br><br>"I'm not scared of you, lady. You're weak. My daddy is strong, handsome, and brave. He will always protect me," Amy repeated.<br><br>At this point, the restaurant was in an uproar. A few people were standing up, security was walking toward us, and our waitress was calling the cops. I pulled Amy out of the diner and into the parking lot, where I sat her in our car and locked the doors. Amy was screaming and punching the glass, repeating the same line over and over. <br><br>"I'm not scared of you, lady. You're weak. My daddy is strong, handsome, and brave. He will always protect me."<br><br>I sat down on the ground, trying to think of a way to help Amy. She might need some professional help, I thought. And maybe the lady in the walls needed to be dealt with, too.
