These days, “X-Files” fans have to rely on Fox’s “Fringe” and Syfy’s “Warehouse 13” to get their weird-science fix, but tonight, they have an opportunity to hang out with the fans of CBS’ math/crime drama “Numb3rs.”

In “Dreamland,” written by series creators (and spouses) Cheryl Heuton and Nicolas Falacci and directed by Stephen Gyllenhaal (father of Jake and Maggie), strange, possibly paranormal events at a decommissioned air base culminate in a woman’s death.

This brings in FBI agent Don Eppes (Rob Morrow) and his mathematician – and part-time crime-solver – brother, Charlie (David Krumholtz).

For Scene 31, Don’s team is consulting with Floyd Mayborne (John Michael Higgins) of the Pentagon’s high-level Department 44. They’re examining some sort of a flying probe that has proved a menace to both humans and farm animals.

Mayborne risks dirtying his dark windowpane-check suit to crawl underneath and take a look.

“That was the director’s idea,” Higgins says, “because I would never get my hands dirty like that – although I wouldn’t have put it past me. I was just a little lazy.”

As a math professor, Charlie isn’t comfortable with the idea of the paranormal.

“It’s a little out there for our show,” Krumholtz says. “It’s cool, the whole alien-conspiracy thing. Charlie, he hates conspiracies. Anything that doesn’t scream ‘logic’ screams ‘absurdity.’ … Of course, the government’s involved. It’s the government being bad again. Bad government.”

Charlie isn’t too nuts about probes, either, and neither is Krumholtz.

“Who hasn’t been abducted?” he quips. “I have been. I’m abducted about once every couple weeks. There’s a lot we’re not being told about, but that’s fine. There are aliens among us.”

But seriously, all this seems a little frivolous for a drama that usually deals with higher math and high crimes.

“The network said,” Heuton explains, “that they were hoping all their Friday night shows could do something Halloween-themed, something spooky.”
