Hungry ghost is a term used in Buddhist and Taoist cultures to describe a spirit that is constantly seeking to fill an insatiable hunger. In Chinese culture, the term "pretas" is often used to describe these spirits. Other synonyms for hungry ghost include "devilish beings," "lost souls," "sinful ghosts," and "starving spirits." These spirits are believed to be trapped between the living world and the afterlife, unable to move on due to their attachments and cravings in their past lives. Many Asian cultures believe in offering food and other offerings to these spirits during ghost festivals to appease their hunger and to bring peace to their restless souls.
