Cosmology of sleep
When the Soul Left the Body Each Night
Egyptians believed that dreams were a gateway to Duat – the underworld and realm of the gods. Sleep was a "little death" in which the soul (Ba) left the body and traveled between worlds. Every night was a journey; every morning, a small resurrection.
The hieroglyph for "dream" (rswt) depicts an open eye – a profound paradox: in sleep, a different kind of vision opens. The Egyptians understood what neuroscience confirmed millennia later – that the dreaming brain is extraordinarily active, not passive.
This was not folk belief but state religion. Dreams were considered divine communiqués, and pharaohs employed professional dream interpreters – priests known as "Masters of Secret Things" (wab seshta) – whose interpretations could shape military campaigns, temple construction, and succession.
