I headcanon that Batman has PTSD (very much implied in canon) and OCD
Bruce's intrusive thoughts/obsessions/compulsions include:
- paranoia that someone can read his thoughts at all times, which really sucks considering J'onn is with the JL
- needing to check his kids are breathing at night (typically done for babies) and if he doesn't do this he believes he has doomed them to die by not checking
- showering/washing hands if he can't shower, at least 3 times after patrol (more if it was a hard night, and he gets into a cycle if he doesn't do it right. This makes his skin really dry and itchy)
- he needs to check the cowl is on several times in a mirrored surface even though he can feel it on his face and knows its irrational
- one obsession is a constant fear of harming himself or others, either indirectly or directly (eg deliberately harming his children or accidentally killing them all by setting the house on fire by leaving the oven on)
- the "trophies" in the batcave is actually the only type of hoarding he can't overcome the compulsion for, because they might be useful someday (except the dinosaur. That's not a compulsion, he just likes dinosaurs)
- he often repeats nonsensical words in his head, either because he can't stop it or to avoid intrusive thoughts
- he will think of "neutralising" thoughts to counter obsessive thoughts, especially on patrol
- when thoughts of harming others get too bad, he will pull his hair, which helps only slightly
- he always does 3 out loud and 5 mental headcounts before and after patrol, so he's really upset when Dick or Jason aren't present because he can never be sure if they're out that night and if they returned
- he avoids Crime Alley to avoid both a PTSD attack and to avoid the intrusive thoughts that say it was his fault (in a lot of his canon dreams the gunman is a distorted version of the Batman)
