What is phantasmagoria definition?

Phantasmagoria is a form of theatrical entertainment that was popular in the 18th and 19th centuries. It involved the use of magic lanterns, special effects, and live performances to create frightening and supernatural illusions for the audience. The word phantasmagoria is derived from the Greek words "phantasma" meaning "ghost" and "agora" meaning "to gather," and it refers to the gathering of ghosts and other supernatural beings. Phantasmagoria shows were often associated with the Gothic genre and were known for their eerie atmosphere, dark themes, and innovative use of light and shadow. Today, the term phantasmagoria is often used more broadly to refer to any kind of eerie or unsettling experience or situation.
