and on at least two occasions the neighbors' complaints about noise when he crashed back to the floor required relocating the experiments to someone else's apartment. Allegedly a control personality emerged who claimed to be Konráð Gíslason, Indriði's grandfather's brother, who had been a professor of Icelandic language at the University of Copenhagen. Spiritualist believers claimed that in the first year of experimentation, knocks were heard on the wall and lights manifested, initially as flashes or spots in the air or on walls, up to 58 at a time, of various sizes, shapes, and colors, and in early December 1905, a man appeared in the light. Their accounts report that the lights, which "as in all his major phenomena, seemed to cause [Indriði] much pain," so that he would "shriek and scream" and complain after the séances that he "felt as if he had been beaten up," stopped at Christmas but resumed in December 1906, when a man again appeared in the light and claimed to be a discarnate Dane named Mr. Jensen. The man supposedly appeared several times in a pillar of light that observers described as very beautiful, while Indriði this time sat in a trance. Proponents defend the genuineness of the phenomena, saying that no equipment capable of producing the lights was available in Reykjavík, and the Kvarans attested that Indriði had only a single footlocker with no lock, and they and others searched him and kept him under observation. Spiritualists claim that on his first appearance, Jensen spoke audibly, asking "in a typical Copenhagen accent" whether people could see him and that he was also palpable: he attempted to touch people and let them touch him. According to their accounts, in January 1908, a being named Sigmundur manifested, audible at some distance from Indriði. Spiritualists report that after that there were occasions when several voices were heard around Indriði while he was visiting his fiancée on a farm, including one outdoors in broad daylight when multiple different voices spoke to him and each other, in immediate succession and even simultaneously. Proponents say that an observer who suspected him of ventriloquism reported that he once heard a male and female voice singing simultaneously in a skillful and trained manner, a supposedly impossible feat for Indriði, who was described as an untrained singer who used to sing in the cathedral choir. Believers cited an anecdotal story that a
