Interesting article on sleep

I like this quote about the sleeping mind's ability to tackle difficult problems: "open the aperture of memory"

Greek perspectives of dreaming

In an earlier post I discussed a dream in Homer's The Odyssey.

Ancient Greeks believed that dreams were external forces that revealed themselves to the sleeping mind...hence the phrase "visited by a dream".

According to Homer, Dreams dwell on the dark shores of the western Oceanus (Od. xxiv. 12 ). The deceitful dreams would come through an ivory gate, while the true ones issue from a gate made of horn. (Od. xix. 562, &c.)
