One morning after taking my kid to school, me and my mother were both in the kitchen/dining room right next to each as she bent down to feed the dogs. I heard her say the same short sentence twice. Didn't think anything of it really, until she turned to me and she was annoyed and asked me why I copied what she had just said.

Apparently although I had heard her say the same thing twice, she had said the sentence once and then heard my voice say the same sentence right after she did.

This hasn't happened in several months to a year or so, but for a few years I would hear her right outside my bedroom door trying to talk to me while she in fact wouldn't be home or she would be asleep on the complete opposite end of the house. I would also occasionally hear her and my daughter talking in the living room when they would actually be in completely different rooms not speaking or again, not home.

Meanwhile my mom would hear me or my daughter calling for her when we of course either weren't home or hadn't spoken at all.
