What is mirror on the ceiling meaning?

Mirror on the ceiling typically refers to a mirrored surface placed on the ceiling of a room, often in bedrooms or bathrooms. This is a popular feature in hotels or adult entertainment venues meant to enhance the aesthetics of the space and provide a sensual atmosphere. The phrase "mirror on the ceiling" can also be used metaphorically to describe someone who is self-absorbed or narcissistic, as in the song "Hotel California" by The Eagles. However, in this context, the meaning is often playful and suggestive rather than negative.
