Within the depth-psychological corpus, the Troll figures as one of the most sustained and symbolically weighted embodiments of primitive spiritual possession — a force that drains human vitality, severs relatedness, and petrifies living culture into inorganic stasis. Marie-Louise von Franz is the dominant voice, treating the Troll not as a mere folkloric monster but as a psychic complex of the first order: an archaic nature-spirit that, when it overwhelms the ego, dehumanizes entire collectivities and suspends the capacity for warmth, affect, and human connection. Von Franz reads the Troll's bloodlessness — and his habit of absorbing his victims' blood — as a precise mythological image of fanatical possession, wherein ideological or spiritual inflation evacuates normal human feeling. The Troll also appears as the suppressed pagan substrate beneath Scandinavian Christianity, a counterpart to the black wizard in Mediterranean psychology, and as the negative animus of a woman utterly in thrall to an underworldly quasi-divine principle. Jung's index entry — troll or 'treader' — anchors the term etymologically without elaborating its psychological valence. Across the corpus, the Troll's destruction is never merely heroic: his blood, rightly returned, redeems the kingdoms he has frozen. The term thus marks both the problem of primitive spiritual inflation and its paradoxical cure: the very power that petrifies contains, within itself, the substance of redemption.
the troll has stolen or attracted all life and emotion away from the human realm where it belongs, and thus brought the people into a state of possession.
Von Franz identifies the Troll's core function as the psychic theft of vitality and affect, producing collective possession indistinguishable from political or religious fanaticism.

the troll would represent a spiritual primitiveness so great that it kills all relatedness... if an individual or a group or even a whole nation is filled with the primitive spiritual possession of some ideological ideal... they are dehumanized.
Von Franz articulates the Troll's psychological meaning as a form of spiritual primitiveness that annihilates relatedness, directly equating it with ideological fanaticism and collective dehumanization.

the troll represents the suppressed form of pagan elements in Scandinavia.
Von Franz situates the Troll as the culturally specific shadow of Scandinavian Christianity, homologous to the black occultist wizard in Mediterranean psychology.

the princess has communion, so to speak, with the troll in an unholy way... as if he were a secret king or even a godhead of the underworld with whom she communes.
Von Franz reads the princess's ritual dance with the Troll as a form of negative animus possession carrying the structure of unconscious religious devotion to an underworldly deity.

the troll is a secret power that has frozen up, so to speak, estranged from all human warmth.
Von Franz characterizes the Troll as an archetypal force of cold estrangement, associated with the inhuman whiteness of the Arctic unconscious and the freezing of vital human relatedness.

the third year he came again, but had become a real troll and he looked awful... he said that he believed in Trunt, Trunt, and the Trolls in the Mountains, and he disappeared.
The folkloric account of gradual transformation into a Troll illustrates the process by which unconscious nature-spirit possession progressively severs a human being from community, religion, and identity.

the troll has bewitched the people and the animals and every living thing in these three kingdoms, transforming them into lifeless matter.
The Troll's enchantment of three kingdoms into silver, gold, and diamond forests represents the paradox of apparent perfection as psychic petrification — the alchemical goal inverted into a cursed state.

The dancing princess fulfills all these things with the ugly troll. But here something that could be of redeeming religious significance has turned negative.
Von Franz interprets the princess's nightly dance with the Troll as a perversion of sacred, life-restoring ritual movement into a compulsive nocturnal communion with destructive unconscious forces.

this white girl is a cool, deadly feminine shape, ghostlike, that lures the princess to the troll. But she also has that gold needle which can kill it.
Von Franz identifies the white girl as the Troll's instrument and simultaneously as the vehicle of his destruction, exemplifying the principle that the healing factor is concealed within the very agent of pathology.

most neurotic symptoms are like troll skins covering up important positive contents of the unconscious.
Von Franz employs the troll skin as a direct clinical metaphor, arguing that neurotic symptoms function as concealing outer layers that mask unrealized positive unconscious contents.

the troll is killed and the people he had cursed were redeemed with his blood.
Von Franz uses the Troll's redemptive blood as the standard against which the Spanish tale's incomplete resolution is measured, underscoring the necessity of genuinely confronting and destroying the possessing complex.

the silver, golden and diamond forests are cursed kingdoms which are turned back into human kingdoms with a drop of the troll's blood.
The blood motif is identified as the crucial narrative key distinguishing the Danish from the German version, establishing the Troll's destruction as the means by which petrified kingdoms are restored to human life.

she belongs to the troll, spreads unconsciousness, and carries the weapon with which the troll will finally be killed: the needle.
The white girl's paradoxical relationship to the Troll — belonging to him yet bearing his death — exemplifies von Franz's structural principle that the complex's resolution is encoded within the complex itself.
