This morning I dreamt I went to visit the house of some friends. It was an unusual house in that there was a long low movable wall around its perimeter. At several points in the wall there were gaps to take the place of doors. You could move this wall with a simple push and get the openings to fit to the door of each room in the house. It was like opening the lid of a pepper dispenser. You push the lid around and different size holes become available depending on whether you want a light sprinkling of pepper or a great handful.

My friend’s daughter was in her room. I call him my friend but he’s more my husband’s friend. I have an ambivalent relationship with my husband’s friend, but somehow my feelings about him did not feature in the dream nor my feelings about his daughter, who is a strange person I find in real life, though in the dream she seemed normal.

She had gone to a great deal of trouble to tidy her room and yet I noticed the drawers were bulging and stuff peeped out through the cracks of the wardrobes as if she had simply stuffed things inside willy-nilly. There was a false sense of order here.

My youngest daughter who in the dream was still a toddler joined us. A carefree, cheerful toddler. Then a little ball of fur on legs walked across the room. It looked innocent enough and I asked my friend’s daughter what it was.

‘Stay away from them,’ she said. ‘They’re trouble.’ The ball of fur suddenly let out a spray of the foulest stench imaginable into the room and we all reeled back.

‘That’s what they do,’ my friend’s daughter said. ‘And if they manage to get some of that stink on you, it sticks for ages.’

I swooped up my daughter and tried to escape the monstrous ball of fur, which I felt sure was getting ready to spray us again.

The doors slid around the room and my friend, my husband’s friend arrived, all bluster and swagger. He remonstrated with his daughter for keeping the walls fixed in one place. He had had trouble getting in.

I was aware as if in a flash that there were other dangers lurking here in this oddly designed house and I must be careful.
