The play A Dream Like a Dream is considered Stan Lai's work of "self-reveal". He is willing to deal with what really matters him in life by exerting concepts from Tibetan Buddhism. To Stan Lai this is a kind of disenthralment. This work contains his attitude and perspectives on creation. Are we looking for art in life, or life in art? This is a crucial point linked to greater force after Stan Lai's long-term practice in Tibetan Buddhism. Not only can we see the strong connection between the temporary conclusion of his creation, A Dream Like a Dream, and the Tibetan Buddhism, but also the influence can be traced in his earlier works. Moreover, Lai asserts that the difference between dao chang (the place where rites are held) and theater is never just on space. He dose not want to find the way that mind is attached to his works, but Tibetan Buddhism is no doubt the groundwork of his creation. In his early works the connection is hidden and gloomy until A Dream Like a Dream directly shows it. This paper aims to illuminate how Stan Lai conjoins his practice in Tibetan Buddhism with his theatre creation, and to find a much clearer position for his works in the theater of Taiwan.
