I'd be interested in hearing any other people's experiences, but this just happened to me... I was looking at a webpage while at work and the screen darkened like it does when a lightbox pops up over the page, like for an ad or sign-up form. However the pop up never appeared, so all I got was a darkened screen; and all I could think was 'a public event is happening' Haha. Damn. #toomuchDestiny
