A good section to have is one on concept/process issues you encountered, which I think is a generalization of your question about panic.
For instance, you might be mistaken about the operation of a system in some way that prolongs an outage or complicates recovery. Or perhaps there are complicated commands that someone pasted in a comment in a Slack channel once upon a time and you have to engage in gymnastics with Sloogle™ to find them, while the PM and PO are requesting updates. Or you end up saving the day because of a random confluence of rabbit holes you'd traversed that week, but you couldn't expect anyone else on the team to have had the same flash of insight that you did.
That might be information that is valuable to document or add to training materials before it is forgotten. A lot of postmortems focus on the root cause, which is great and necessary, but don't look closely at the process of trying to stop the bleeding.
