If you were on social media around 8pm EST or so Sunday night, you may have seen a few alerts come across your feed about weird happenings afoot at 1600 Pennsylvania Avenue.

Some of you already know exactly what I’m talking about.

For those who didn’t see it last night, cameras trained on the front of the White House caught strobing red lights coming from two second floor windows.

Weird, right?

I’ve heard a lot of theories this morning about what those lights may have been, most of them very tongue-in-cheek, at best.

So, barring the possibility of an inter-dimensional portal opening or the lord of darkness holding an audience with his minions, what have you heard? What are your theories?
