n. peace of mind after a pleasant dream.


Thanks to Google, I found this word defined on about a dozen different sites. Not one defined it with any alternate phrasing (though most can't spell "pleasant"), and none gave derivation info. I can tell you that phrenes is Latin for "delirium," and "eu-" generally denotes something pleasant (euphoria, euphony).

Editor's note. Originally noded as 'euneirophrenia'. This should be euoneirophrenia, from all Greek roots: eu 'well', oneir- 'dream', and phren- 'mind'. - Gritchka
