isposed by the action of the drug, you have
experienced the rush of these forces in undiluted strength. They wholly
obliterate in you the sense of humour, fancy, imagination,--all that
makes for cheerfulness and hope. They seek, though perhaps automatically
only, to oust your own thoughts and establish themselves in their place.
You are the victim of a psychical invasion. At the same time, you have

artificially trained psychic, and consequently aware of the presence of
discarnate entities as a rule, I have so far felt nothing here at all.
This makes me sure that the forces acting here are of an unusual
