Batman: The Animated Series Re-Watch: Episode Twenty Eight: Dreams in Darkness
Plot: Batman is locked up in Arkham. A flashback reveals he was exposed to fear gas, crashed the Batmobile and was imprisoned by the well-meaning Arkham staff. Now Batman must escape his straightjacket and stop the Scarecrow from infecting the whole city with fear.
Another psychologically interesting episode of Batman, one that lays his flaws on table, specifically his inability to trust others. As he did in Appointment in Crime Alley, Batman cannot see a crime about to be committed and not step in, even when leaving the problem for the police is probably the right thing to do.
After being exposed to the fear gas, Dr. Wu gives Batman a clear choice: he can take the antidote, recover for two days, and let ANYONE ELSE, specifically Robin or Commissioner Gordon, handle the Scarecrow in the meantime, or he can delay recovery and try to take care of the Scarecrow himself. And Batman makes the obviously wrong choice. In trying to ignore the problem, Batman nearly kills himself in a car crash and gets himself locked up, cut off from his allies, all while the Scarecrow comes closer to launching his attack.
Notably, in the narration that covers the first half of the episode, Batman admits to two mistakes (he's wrong about the nature of the robbery, and he's wrong about the effect of the gas), but he never admits it was a mistake to drive to Arkham while under the influence of a powerful hallucinogen.

Which makes the final image so psychologically interesting. After rejecting Alfred and Dr. Wu's offers of help earlier, Bruce has submitted to Wu's treatment, administered by Alfred, as he sleeps in the Batcave (and not, say, his very nice bed in this very nice room upstairs). Bruce actually thanks Alfred, saying "It's good to know I'm safe here," so Bruce is learning to accept that he needs help.
Then a very angelic looking bat casts a very Batman-like shadow on Bruce, which suggests that the Batman persona, like Alfred, is a shield that protects Bruce while he recovers. Just as it's the screech of a bat that wakes Bruce from his worst delusion of the episode, being Batman isn't a madness. Being Batman is what keeps Bruce sane and helps him recover from the trauma of the loss of his parents.
That one of Batman's greatest is his villains is new. We've seen his fear of the loss of his parents before, and we saw in The Forgotten that the Joker haunts Batman's thoughts, but now we see a fear of new villains, Poison Ivy and Two-Face, whom Batman has only fought once (and it's only implied that Batman has fought the Penguin before I've Got Batman in my Basement.) We are watching a transition from Batman encountering villains for the first time in the middle of schemes unrelated to him, to villains like the Scarecrow actually setting traps for Batman, targeting him directly. The Joker has been doing that since his first episode, but this episode (and The Clock King) implies more villains are going to act like the Joker, and Batman's job is only going to get harder from hear on out.

Unfortunately, in order for the episode to work, Dr. Bartholomew, head of Arkham, has to be completely negligently incompetent. The Animated Series has a dim view of psychology, and psychiatrists and psychologists on the show range from merely ineffective, like Harvey Dent's therapist, to the outright evil, like Professor Jonathan Crane himself, and while not malicious, Dr. Bartholomew totally misdiagnoses Batman while he ignores everything Batman has to say.
The episode shows Batman DOES have problems trusting people and probably could use therapy, but that would require a psychiatrist who actually listens to him. Instead, Bartholomew diagnoses Batman off just the fact that Batman came to Arkham as someone who cannot tell reality from delusion, when in fact, being Batman, being a detective, is exactly what allows him to see through his hallucinations. But Bartholomew refuses to believe that Batman's hallucinations are gas-induced, calling it "supposed gas", as if the Scarecrow hasn't been using fear gas from the beginning. He refuses to contact Gordon or Dr. Wu like Batman asks, and even after discovering the Scarecrow missing, which proves Batman is right, insists on keeping Batman locked up.
The worst moments is when he chides Batman for not using the villains' real names, which is doubly stupid. I don't think Batman has yet referred to Two-Face or Poison Ivy as anything other than "Harvey" and "Isley", and NO ONE calls the Joker anything but the Joker. His reference to "Jack Napier" is the Joker's real name from the Burton film, but it's never mentioned again in this cartoon. Also, who is Bartholomew to talk? He's the one who leaves them in their costumes, reinforcing their villainous personas over their civilian ones.
Similarly, his explanation that the orderly cannot remove Batman's mask because Batman might become catatonic is utterly ridiculous. How are you supposed contact his loved ones if you don't know who he is? How do you know it's really Batman and not some idiot in a Batman costume? And how could it hurt to take off his mask while he's out of it, if you put it back on before he wakes up? Maybe Batman would learn to trust people, if he wasn't surrounded by idiots.

(Strangely, the interior of Arkham in Fear of Victory, with glass enclosed cells of concrete, looks very different from the one in Dreams in Darkness, where cells are made of stone and closed by iron doors. Considering we also don't see any other famous Arkham inmates, except in dreams, it's possible that Batman was thrown into the arcane practices wing, while the costumed villains are kept somewhere else.)
That said, once you get past those problems, this is a pretty great episode designed to get us inside Batman's head. The noirish narration, the superb dream sequences, the flawed hero, and the comforting image of the bat protecting Batman, closes out the season with style.
