Some we see no more Tenements of Wonder — Oneirocriticism

Oneirocriticism is the art of interpreting dreams, hinted by Conjecture in line five. Conjecture has the definition of "interpretation of dreams."

Some we see no more, Tenements of Wonder 1
Occupy to us though perhaps to them
Simpler are the Days than the Supposition
Leave us to presume

That oblique Belief which we call Conjecture 5
Grapples with a Theme stubborn as Sublime
Able as the Dust to equip its feature
Adequate as Drums
To enlist the Tomb.
(F.1210/J.1221)

Cicero tells one or two pertinent stories, by the transcription of which the juggling, ambiguous mode of the oneirocritic may be pleasantly exposed. . . . 'Do not the conjectures of the interpreters of dreams rather indicate the subtlety of their own talents than any natural sympathy and correspondence in the nature of things?' ─ The Literature and Curiosities of Dreams (1865)

And Cardan, who dreamed that he discoursed with his dead father in the moon, made thereof no mortal interpretation; and even to dream that we are dead, was no condemnable phantasm in old Oneirocriticism, as having a signification of liberty, vacuity from cares, exemption and freedom from troubles unknown unto the dead. ─ Miscellaneous works of Sir Thomas Browne (1831)
