The Honest Trailersepisode about Ghostbusters has these words in the Starring section: "Egon, but not forgotten".
Small but surprisingly sweet, in the expanded universe that includes the comics and animated adaptations, it is revealed that despite wanting to get out a lot of the ghosts that get busted are relatively happy inside the containment unit. It's not the same as passing on to whatever comes after but for a lot of them who won't ever move on or who don't have the option its a nice respite from the chaos of the mortal world and they've made peace with being inside for the long haul.
