Why are there no windows in the the castle of Dracula?

The absence of Windows in Dracula's castle serves multiple purposes, both practical and symbolic. Practically, it enhances security and privacy, making the castle more formidable against intruders. Symbolically, it reflects the isolation and darkness associated with Dracula himself, emphasizing themes of confinement and the supernatural in Bram Stoker's novel. This lack of natural light further contributes to the eerie atmosphere of the setting.
