According to Catholicism, does reception of the gift of the Holy Spirit protect against demon possession?

A Catholic answer to this question regarding instances of animal-like behaviors in spiritual movements in history included reference to the Loudon possessions in 1634 in France in which a group of nuns were possessed: > The nuns claimed the demon Asmodai was sent to commit evil and impudent acts with them. During questioning about the supposed evil spirit thought to be possessing them, the nuns gave several answers as to who caused its presence: a priest, Peter, and Zabulon. > > The nuns' increasingly extreme behavior: shouting, swearing, barking, s etc. drew a considerable number of spectators. A comment questioned the implications for the salvatory state of the nuns: > An interesting thing is that the Scripture strongly indicates that born-again believers (indwelt by the Holy Spirit) cannot be possessed by demonic spirits, so what does that indicate for the Nuns? The responding comment was that Catholic exorcists and Catholic hagiography indicate differently: > Catholic exorcists would genuinely disagree with that opinion. This is not the place to start an argument, on this subject. Catholic hagiography actually supports it, as happened to even a few canonized saints. The Devil hates the truth! My question is: Does the Catholic Church actually teach that believers who are indwelt by the 3rd person of the Trinity can still be demon possessed? Do Catholics have reason to fear that they might get possessed?
