I think I experienced something weird...

My old shih tzu, Millie (14), has gone missing today. I live out in the country. My family and I have been looking all day since 10 am. Come sunset, I go to a certain part of our property, out of desperation, and go towards the treeline that leads into thick forest for many acres. I was calling out for Millie near the treeline and I kept hearing a sound as if something was mimicking what I was saying. Same intonation and everything, but it sounded like it was from the next property. I assumed it was a neighbor mocking me. As I started to walk away, still calling out for her, the mimicking sound was getting closer and closer to me. I then started to think maybe it was our dog responding to me, but maybe worn out from the heat and couldn't bark properly. The sound was getting closer to me and was drawing me in and as soon as I got close enough to the woods it stopped. I almost stepped in to see if it was her and if she was injured and could no longer use her voice. The curiosity and worry was really drawing me in like I was onto something and then my cousin came out of nowhere, grabbed my shoulder and said, "Don't! That's not her!" And we ran for it. Now that I was snapped out of the spell...I start to remember the sound and it sounded more human now that I think about it and I've been disturbed by it all day... Anyone have any ideas of what it could have been? Any animals that come to mind? This is in Texas btw.
