How totally...bizarre

This one woke me up before my alarm could go off, and it's not even a real dream, just a snippet of "information" that is so off-the-wall that I'm not sure what to do with it, or where it came from:

Turns out my brother's wife left him about 6 years ago and he's been lying to us ever since.

My first thought upon waking up? "But, haven't I talked to her since then??"

Yes. I have. Dozens of times. I've even seen her, at their house in Arizona, within the last 5 years. I like her, too, so it definitely isn't wish-fulfilment.

So. What the heck does this mean?
