DS9 Season 1, Episode 16: "If Wishes Were Horses." Classic. We've already done The Naked Time twice, so... everybody's imaginations come to life. Because of aliens. For Dr. Bashir, it's a sexed-up, totally submissive, dumb-as-a-box-of-hair Jadzia Dax trying to climb into his pants. (Classy.) For Ben and Jake Sisko, it's one of the last great baseball players, Bokai of the London Kings, who wanders around trying to get them to play baseball rather than do their work. For Chief O'Brien, it's Rumpelstiltskin. CHIEF O'BRIEN, WHAT IS YOUR PROBLEM. Everyone's imaginations run wild all over the ship, and Quark makes fun of Odo for not having one, although if I had to guess who was introducing all these minor disturbances that only Odo can deal with, I'd pretty much choose Odo. Quark imagines hot bitches until he realizes that people are imagining winning constantly at his gaming tables and then he gets depressed. Some kind of random Trekky rift opens in space and threatens the station unless they can do something scientific within a set time limit. The imaginary creatures have a creepy little meeting, where we learn that, yet again, ALL IS NOT AS IT APPEARS. Sisko and the gang try to fire missiles into the rift, which should for some reason make it collapse, but instead it gets worse. Rumpelstiltskin offers to fix the problem if O'Brien will trade his wife and daughter and O'Brien agrees way too fast. No idea why Keiko isn't murdering him hardcore by the end of the episode. Sisko suddenly realizes that Jadzia imagined the rift and that they can all just pretend it's not there, and, lo and behold, everything disappears. O'Brien takes his wife and daughter home with no signs of imminent murder. Bokai comes back to have a deep conversation with Sisko about how the imaginary creatures are actually explorers. Sisko doesn't get pissy at him for threatening DS9 with imminent destruction, even though, yes, technically Dax imagined the rift. She wasn't the one who made it TANGIBLE, you know.
