I have spoken with spirits about what sirens are, and I was informed through angels that sirens are those who steal into the passions, pleasures, and feelings of another in such a way that those in the process of slipping in do not know that evil or deceit underlies it. Thus they are caught up in enjoyment together with the others with whom they are in company, and yet, although they do not think on this at the time, still when the chance arises, some evil intent shows itself, either of getting hold of their possessions, or of cheating, or of killing them, and the like. Those, however, who while stealing in meditate on deceptions, and thus act deliberately or slip in studious of an evil purpose, they are not sirens, but deceivers. 1748, 28 Aug.
