n. (plural of phantasma English)
Wikipedia
Phantasmata is an orchestral triptych by the American composer Christopher Rouse. The title is derived from the works of the occultist Paracelsus, who described phantasmata as "hallucinations created by thought." Rouse originally composed the second movement "The Infernal Machine" as a stand-alone piece in 1981, though he later elected to make it the second part of a larger work. Phantasmata was commissioned in full by the St. Louis Symphony and a fellowship grant from the National Endowment for the Arts and completed March 22, 1985.

It was natural enough to Jack, who had known this state of affairs since he was a child, but it was the first time that Stephen had met with it, and it gave him a not altogether disagreeable sensation of waking death: either the absorbed, attentive men on the other side of the glass wall were dead, mere phantasmata, or he was - though in that case it was a strange little death, for although he was used to this sense of isolation, of being a colourless shack in a silent private underworld, he now had a companion, an audible companion.
