"Wait!" Zhou Xuan raised his hand to stop him, then asked, "Do you feel hungry?"
"Hungry? Now that you mention it... A Hunger Dream?" Qing Feng responded.
Li Chengfeng, Zhang Yifeng, and the other five night watchmen also began to notice their "sense of hunger" after Zhou Xuan's prompt.
Zhou Xuan had experience with this kind of situation. Back at the Forbidden Tower of Qiye Temple, Monk Zhu Jiu had taught him that the offspring of Divine Alien Ghosts inherently possess Physical Body Dreams.
These dreams are akin to a sort of Forbidden Land, impervious to incense offerings. Once you step into their dream's domain, it contaminates your consciousness and spirit.
Those with strong incense offerings might have some resistance, allowing them to escape the dream's grip before their mind is completely overtaken, preserving their life.
But if they refuse to leave, their mind will be continually eroded until it's entirely controlled.
