I've had several experiences with this, as well as one of my friends who Swears Stephen Hawking was Dead and only realized he was not when she heard it on TV, maybe he celebrated a birthday or something. So she apparently was living in a timeline in which Hawking was dead, and got Shifted into one in which he was Alive. Something else must have changed as well.
Hmm. The far more likely explanation is that she merely 'thought' he was dead and convinced herself of it.
People talk about 'timelines'....when it's worth pointing out that to date there is not the slightest scientific evidence they exist. None. Zilch. There is more evidence for leprechauns at the end of my garden.
