Where is your "holiest-of-holy" place. In otherwords, where is your den.
Mine is the middle room: it's an area where all the dresses, suits, blankets, towels & suitcases are haphazardly stored. There is an L-shaped or elbow lounge spanning the north & east walls that is obscured by pillows. The west wall is lined by towering tallboys, crammed with paraphernalia. When the washing-machine is turned on, I enter the room, drag the heaviest suitcase in front of the door (which usually doesn't close) and drown in the pillows with a book. Since the bedroom in my childhood abode, this has been the one place where I can engage fully in fantasy & be severed from all else.
