I took a normal selfie last night before bed and posted it, then deleted it because I didn’t like how I looked. But this morning it was back on my phone, except it wasn’t normal anymore. In the background of the photo there’s someone standing behind me. The weird part is I live alone. I tried deleting it again and my gallery refreshed by itself. Now there’s a new photo uploading… taken from behind me right now.
