One more room
My mother, who grew up in a house that was a little bigger than the one she raised me in, regularly dreamed of finding another room in our home. I actually dreamed about finding an extra room, too, sometimes.
Weirdly, though, I don't think I've ever dreamed about finding another room in my current house. In fact, even in middle age, I'm more likely to dream about the house at Home Farm, and very rarely dream about my own home where I've loved for thirty two years. Once I dreamed that I opened my childhood closet and there was a whole extra passageway and room off to one side of that.
I would very much like to have a dedicated studio space, even a very small one, instead of my current system (in which I balance a canvas on my knees and the edge of my computer desk if I'm painting from a photo reference.) Not going to happen any time soon, though.
