Dream-world = Mental plane (MANAS maya-kos`a)

goddess MANASa = goddess Janguli – Bengali goddess "Manasa has an affinity with the Buddhist snake-goddess Janguli" (Umakant Premanand Shah : Jaina-rupa-man.d.ana : Jaina iconography. Abhinav Publications, 1987. p. 278) (also mentioning Jaina snake-goddess Vairot.ya) http://books.google.com/books?id=m_y_P4duSXsC&pg=PA278&lpg=PA278&dq=janguli&source=bl&ots=3wGEbtUFg1&sig=11StyuDmFNPQ9NTy6IJcK05TDa8&hl=en&ei=txBiSunOJ8S_tgeq1OD0Dw&sa=X&oi=book_result&ct=result&resnum=10

with the name of /JANGuli/ cf. the name of /ZANGara/, the Sumerian "god of dreams" (Black; Cunningham; Robson; Zo’lyomi : The Literature of Ancient Sumer. Oxford U Pr, 2006. p. 372) http://books.google.com/books?id=a1W2mTtGVV4C&pg=PA372&lpg=PA372&dq=dream+"divine+spouse"&source=bl&ots=61id-tBpXp&sig=S1eOOAW_h0lkLA9vhMNtjug7osc&hl=en&ei=eA1iSrv8NomEtgf7n5j1Dw&sa=X&oi=book_result&ct=result&resnum=3

Sumerian /ZanGaRa/ may be cognate with <ibri^ /ZeKeR/ ‘memory’ : just as the Hellenic word for ‘memory’ is /MNeme/, returning to Samskr.ta /MaNas/ ‘mind’

The overall sense of these meanings may be that dreams abide on the mental plane.
