The standard interpretation of the extra-room dream is that it’s a portent, or just a friendly reminder, of shifting tides. The room represents parts of ourselves that have lain dormant but will soon emerge, hopefully in a good way, but then again, who knows?

The angles are wider, the dimensions far greater than you’d given them credit for.
