On another thread somewhere in Avalon people told similar stories of things like driving the same ordinary street to work and seeing a new building on the corner that was not there the day before.
I also saw a thread somewhere on the web where people were talking about movie stars or celebrities that they were pretty sure were dead, then hearing that they had just died. Since nobody had really paid attention the first time, nobody knew for sure if they remembered it correctly or not.
The metaphysics I know says this 3-D reality, including the property we call time, is like silly putty. Maybe it's just getting sillier as the veil between dimensions gets thinner.
