Yes. Sometimes people allow it by their actions, sometimes God permits it so that His greater glory can be accomplished. I highly recommend [Fr. Ripperger's videos, particularly this one](https://youtube.com/watch?v=TMcvZaiBwe4). Fr. Ripperger is a long time exorcist and shares his experiences and wisdom very openly and bluntly. You may need to research some terms like "[Sanctifying Grace](https://www.newadvent.org/cathen/06701a.htm)" to better understand what he is talking about.
