Ghosts are an important and integral part of the folklore of the socio-cultural fabric of the geographical and ethno-linguistic region of Bengal which presently consists of Bangladesh and the Indian states of West Bengal and Tripura. Bengali folktales and Bengali cultural identity are intertwined in such a way that ghosts depicted reflect the culture it sets in. Fairy tales, both old and new, often use the concept of ghosts. References to ghosts are often found in modern-day Bengali literature, cinema, radio and television media. There are also alleged haunted sites in the region. The common word for ghosts in Bengali is bhoot or bhut. This word has an alternative meaning: 'past' in Bengali. Also, the word Pret is used in Bengali to mean ghost. In Bengal, ghosts are believed to be the unsatisfied spirits of human beings who cannot find peace after death or the souls of people who died in unnatural or abnormal circumstances like murders, suicides or accidents. Non-human animals can also turn into ghosts after their death. But they are often associated with good luck and wealth in Bangladesh.

Bengali literature denotes the body of writings in the Bengali language and which covers Old Bengali, Middle- Bengali and Modern Bengali with the changes through the passage of time and dynastic patronization or non-patronization. Bengali has developed over the course of roughly 1,300 years. If the emergence of the Bengali literature supposes to date back to roughly 650 AD, the development of Bengali literature claims to be 1600 years old. The earliest extant work in Bengali literature is the Charyapada, a collection of Buddhist mystic songs in Old Bengali dating back to the 10th and 11th centuries. The timeline of Bengali literature is divided into three periods: ancient (650–1200), medieval (1200–1800) and modern. Medieval Bengali literature consists of various poetic genres, including Hindu religious scriptures, Islamic epics, Vaishnava texts, translations of Arabic, Persian and Sanskrit texts, and secular texts by Muslim poets. Novels were introduced in the mid-19th century. Nobel laureate Rabindranath Tagore is the best known figure of Bengali literature to the world. Kazi Nazrul Islam, notable for his activism and anti-British literature, was described as the Rebel Poet and is now recognised as the National poet of Bangladesh.
