I feel a strong sense of evil from certain objects in our home, to the point that I cannot look at them without making a concentrated effort to do so. Is it possible for objects to be cursed or attached to evil spirits? If so, what can I do to combat this?
Yes, objects can be cursed, just as objects can be blessed. I suggest that you dispose of the objects that bother you. In his book, Interview with an Exorcist, Fr. Jose Antonio Fortea writes that such objects should be burnt (110).
