I don't remember a huge amount of detail about this dream, but I had a pet mouse, and for some reason I'd decided that I wanted to set it free in my loft.

I climbed up the ladder into the loft, and the loft was absolutely enormous! It was partly boarded in old floorboards, and most of the roof space was tall enough to stand up in with many different sections of pitched roof. It felt like being in the loft of an old mansion or stately home.

I let my pet mouse free and he scurried off in amongst the junk scattered throughout the loft.

Before leaving I started to look around at the items I'd left up here, and came across what must have been an old woodwork project. It was a small wooden box with a lid that was in two parts and hinged in the middle, so that you could open it from either end of the box. I suddenly noticed that one of the sides of the lid was moving on its own, so I sat watching it for a moment. All of a sudden it opened completely and my pet rat (who died a long time ago) was inside!
