Ventola then summarized Rogo’s conclusions: “According to his content analysis, both experiences [transcendental music and out of body events] manifest during similar mental states, and the type of music heard (i.e. choral vs. instrumental or melodic music vs. music without a discernable melody) coincides with the type of OOBE (natural vs. enforced) reported. Rogo’s analysis also uncovers what he calls a ‘crescendo effect’ in the majority of the collected cases, in which the experients report the volume of mysterious music gradually being heard, rising to full power, and receding again.” Ventola ends her review with quite a compliment: “It is admirable that someone so young, without having yet completed a formal education, would not only have the initiative to collect reports about little understood or discussed phenomena, but also have something meaningful to say about them.”
