@Melissa Pier That was one of my favorite movies growing up 🤗 I didn't fit in so I hung out with my imaginary friends and trees . 😄 The fact that you even noticed it and thought of decoding the varying pitches seems significant to me, all my intuitive alarm bells went off like "oh she's on to something ". Hearing your son's say mom is something similar to what I've experienced multiple times and 2 times I accidentally answered people when they didnt say it out loud, they asked me how but I dont actually know because I literally heard it and I'm not even sure what thats called. I always say if we embrace diversity then we can learn a lot from one another because we all hold our own brilliance within us, like a scenic puzzle of a river in the woods and we are each a puzzle piece where we can have similarities being a sky piece, water piece, plants, the ground ect but still unique in the shape ,where we fit in and you need all the pieces to complete the picture. So you recognizing the tones and wondering if theres a morse code to it might be a testament to one of your own strengths, an aspect of the brilliance that you hold within and I hope you explore this more and personally looking forward to whatever you find.🥰
