Never interrupt a faerie circle ceremony. And, if a faerie has appeared to you, visually, do not speak to it until it has spoken to you. These two transgressions are considered so rude, that the faeries may literally attack you, on the spot.

Although terrifying, the evil ghost will probably pose no real danger to you or your family. On the other hand, if you have a demonic infestation, your entire household is in very real danger. A demonic entity will not usually confront you or induce you to flee the home. Because, unlike the evil ghost, the demon does not actually want you to leave. On the contrary, it wants you to stick around so it can destroy your life and sully your soul from the inside.

Never invite any kind of spirit to enter either your home or your person. This is an extremely important point to remember. To do so always risks to unwittingly invite evil spirits in, instead. Good spirits never need to be invited in.

The one plus side to demonic infestation is that children cannot be harmed by a demon. The sanctified aura of a child somehow repels the demon and they can only oppress them if the parent makes a contract allowing them to do so. Because they can be very clever in tricking people into agreeing to additional contracts, it is important to never converse with a demon. Either call in a priest or move out as soon as possible.
