"I suppose now you do not believe in corporeal transference. No? Nor in materialization. No? Nor in astral bodies"

Corporeal transference is the transference of one’s mind into the body of another, so that one can gain control of that body.

Materialisation is the unusual or paranormal appearance of an object or person; this phenomenon is often reported to happen during a séance.

An astral body is something between the corporeal body and the soul, a sort of dream-like body composed of subtle material that can move independently of the physical body (astral projection).

These are all paranormal concepts that science typically rejects. Ideas such as these were very popular in the Victorian period.
