Escapism

From a tender age, Mimi has always treated her precious books as a means of escape to a richer, more colourful, more exciting world. 

So it is kind of normal than in her sleepwalking state she would treat her bookcase as a portal, or at least a door, to that richer, more colourful, more exciting world. 

Being irremediably more prosaic, that bloody Billy bookcase bollix refused to oblige and opted instead to empty its content on top of her. At 2 in the morning. 

Never a dull moment with a sleepwalker in the house...
