The hierophant was a revealer of holy things... It was essential that the hierophant should be a man of commanding presence and lead a simple life. (Dudley Wright, The Eleusinian Mysteries And Rites)

And here, from the venerable hierophant, who from a strict sense of duty had left his sick-bed to come hither and instruct me, the words seemed to possess a peculiar meaning and value; his simple appeal to my own sense of rectitude had all the force of a profound thought extracted from a world of thinking. (Herbert M Vaughan, Meleager)

Origin:
'expounder of sacred mysteries,' 1670s, from Late Latin hierophantes, from Greek hierophantes 'one who teaches the rites of sacrifice and worship,' literally 'one who shows sacred things,' from hieros 'sacred,' from PIE root eis-, forming words denoting passion + phainein 'to reveal, bring to light' (from PIE root bha- 'to shine'). In modern use, 'expounder of esoteric doctrines,' from 1822. (Online Etymology Dictionary)

Hierophant, hieroglyphics, and hierarch have a common root: hieros, a Greek word meaning 'sacred.' Hierophant itself joins the root with a derivative of phainein, which means 'to show.' The original hierophants were priests of the ancient Greek city of Eleusis who performed sacred rites. In the 17th century, when the word was first documented in English, it referred to these priests. By the 19th century, English speakers were using the term in a broader sense. A hierophant can now be a spokesperson, a commentator, an interpreter, or a leading advocate. (Merriam-Webster)

As George Orr slipped into another oneiric state, the fabric of reality trembled. His dreams, potent and uncontrolled, reshaped the world with each passing thought, blurring the lines between imagination and actuality. (Ursula K Le Guin, The Lathe of Heaven)

Origin:

'of or pertaining to dreams', 1859, from Greek oneiros 'a dream' + -ic. (Online Etymology Dictionary)

The notion of using the Greek noun oneiros (meaning 'dream') to form the English adjective oneiric wasn't dreamed up until the mid-19th century. But back in the late 1500s and early 1600s, linguistic dreamers came up with a few oneiros spin-offs, giving English oneirocriticism, oneirocritical, and oneirocritic (each having to do with dream interpreters or dream interpretation). The surge in oneiros derivatives at that time may have been fueled by the interest then among English-speaking scholars in Oneirocritica, a book about dream interpretation by 2nd-century Greek soothsayer Artemidorus Daldianus. In the 17th century, English speakers also melded Greek oneiros with the combining form -mancy ('divination') to create oneiromancy, meaning 'divination by means of dreams'. (Merriam-Webster)
