The 'What If It Was All Just a Dream?' meme is a series of surreal, often melancholic images that depict famous locations or pop culture characters being completely erased from their original settings. The trend gained massive traction around 2020, typically featuring a slightly blurred or 'empty' version of a well-known scene—such as the 'Always Has Been' Earth or the 'Arthur' fist—accompanied by an existential caption. It taps into a sense of nostalgia and 'unreality,' suggesting that a beloved piece of media or a significant historical event never actually happened. The meme is widely used to express a longing for simpler times or to joke about the absurdity of modern reality by imagining it never existed.
