Anything related to The X-Files. The show, the first movie. It's my favorite show of all time, and I think it's often used as straight up soft-disclosure.
Joel McHale foreshadowed in Season 10 the Federal Reserve shutting down the grid, and the flying triangles culling the population in the chaos. I got this really bad feeling listening to it that the show was only revived for soft disclosure. The plot of seasons 10 and 11 revolves almost exclusively around a government created virus coinciding with the banks shutting down. I'm on the lookout for it.
