"I'm writing a play called 4.48 Psychosis. It's about a psychotic breakdown, and what happens to the person's mind when the barriers which distinguish between reality and the forms of imagination completely disappear - so that you no longer know where you stop and the world starts. So, for example, if I was a psychotic, I would literally not know the difference between myself, this table and Dan. They would all be part of a continnum. And various boundaries begin to collapse. Formally, I’m trying to collapse a few boundaries as well. To carry on with making the form and content one. "
