Today was the first day, really. I was outside with my aunt speaking with the neighbors, when I started speaking French with surprising fluency using words I hadn't yet learned. I had minimal control over my mouth and all I could do was lower my voice. I went back into the house and got my notebook and pencil so I could write everything instead of speak, and so it would be easier to translate later. But just as I got to that point, the French stopped. We'll stopped coming from my mouth at least. Since this happened, everything I hear is in French, yet it is almost as if I can understand it. Mind you, I've had only a year of French training so my accent and fluency were not nearly as proficient as they have been today.
Also, there have been mumbles and knocking throughout the house, and my little cousin keeps calling out in small French words like calling for his mother with French pet names and asking for food in French. His mother assumed it was just me teaching him these things, and so I went along with it as to not worry her. If you have read my other story, you will know that I have a short history with communicating with spirits. The fact that I am being used by a spirit is not abnormal, but the fact the spirit has the ability to alter my speech and hearing and understanding of my mother language is a bit unnerving.
Advice is welcomed, but I'd really like to hear any similar situations most. I searched on Google and nothing came up, so I a assume this isn't too common.
