A certain accident untethered 
her imaginality from her body,
Bei einem Unfall haben sich ihr Körper
und ihre Imaginärelemente getrennt
Su cuerpo y su elemento imaginario
se separaron en un accidente
Su cuerpo y su elemento imaginario
se separaron en un accidente
Un accident a causé une scission
entre son corps et son imaginaire,
Pare che fu coinvolta in un incidente
Em um acidente, seu corpo físico e
seu Elemento Imaginário se dividiram
После несчастного случая
её сознание оказалось отрезано от тела…
