Socrates - Plato Crito - Hears music and voices
Type of Spiritual Experience
This is an hallucination, but hearing a humming noise often precedes out of body experiences, though I may be taking this a bit too literally
A description of the experience
SOCRATES: This, dear Crito, is the voice which I seem to hear murmuring in my ears, like the sound of the flute in the ears of the mystic; that voice, I say, is humming in my ears, and prevents me from hearing any other. And I know that anything more which you may say will be vain. Yet speak, if you have anything to say.
CRITO: I have nothing to say, Socrates.
