The Morpheus Nyx Nyx was Morpheus's mother In Greek mythology, Nyx (Νύξ, "night", Nox in Roman translation) was the primordial goddess of the night. A shadowy figure, Nyx stood at or near the beginning of creation, and was the mother of personified gods such as Hypnos (sleep) and Thánatos (death). Her appearances in mythology are sparse, but reveal her as a figure of exceptional power and beauty.

The Morpheus Nebuchadnezzar The name of Morpheus' ship, the Nebuchadnezzar, is a Biblical reference to King Nebuchadrezzar II of Babylon, from the biblical Book of Daniel. King Nebuchadnezzar ('the Great') was famous for his conquests of Israel in Biblical times (specifically Judah and Jerusalem). He also built the Hanging Gardens of Babylon (one of the lost Seven Wonders of the Ancient World) for his wife. He has a dream he can't remember but keeps searching for an answer. Morpheus makes reference to this in The Matrix Reloaded (2003) after the Nebuchadnezzar is destroyed, with the line "I have dreamed a dream; but now that dream is gone from me". Nebuchadnezzar's dream is found in Daniel 2:1-49.
