Andrew has some good dreams: "My previous dreams had occurred in a non-dimensional universe. They had occupied zero time and zero space. They contained no physical presence and nothing actually happened. Instead, they were flooded with fundamentally important concepts I couldn't understand and which can't be expressed through any existing paradigm. They were intangible and impossible to describe physically. And yet, paradoxically, later in the night, after I rolled over and changed sides, the second dream was a perfect optical isomer of the first".
