“On cloud” refers to a state of euphoria, bliss, or extreme happiness. It is often used to describe a feeling of being detached from reality or floating on air. Example: “She was on cloud nine after receiving the good news.”
This expression has been used for centuries, dating back to the early 1900s, and is believed to have originated from the sensation of being so happy that one feels like they are walking on clouds. It is often used to describe the feeling of being in love, achieving a long-awaited goal, or experiencing a moment of pure joy. Being “on cloud” can have several positive effects, such as increased energy, creativity, and a sense of well-being. However, it can also lead to unrealistic expectations or a lack of focus on the present moment.
