Its very possible that the mom part was feeling back in the moment. My little ones often mix up time so they know what's happening in the present time but emotionally feel like things in the past happened a day ago instead of fifteen years ago. It's a weird feeling to be connected to both the present and the past, like both are happening at the same time. Is that how you experienced it at all? Sometimes it's a nice break for me to be in a happy past memory instead of a traumatic one, but it can feel odd!
