Based on a TikTok video released by a user, he shows his experience with what appears to be a supernatural being, and we're out.
In the video the OP is driving at night, on a somewhat lonely and dark street, and as he looks in his mirror at the backseat, he sees a figure in white sitting in the backseat.
He quickly takes a video of the scene through his mirror, and true enough, there is somewhat of an apparition in the backseat.
After awhile he even turns around with his camera to show that there is no one actually physically present in the car, but himself.
