IN addition to the diagnostic valuation of dreams (e.g., by Hippocrates) mention must also be made of their therapeutic significance in antiquity. Among the Greeks there were dream oracles, which were vouchsafed to patients in quest of recovery. The patient betook himself to the temple of Apollo or Aesculapius; there he was subjected to various ceremonies, bathed, rubbed and perfumed. A state of exaltation having been thus induced, he was made to lie down in the temple on the skin of a sacrificial ram. He fell asleep and dreamed of remedies, which he saw in their natural form, or in symbolic images which the priests afterwards interpreted.
