Last night my wife burst out laughing in the middle of her sleep.
She dreamt that I was showing her something on my laptop. It was a row of blocks of sponge in different colours (complete with the green abrasive layer).
I was somehow making them lie down, stand up, and turning them left and right (interactive animation?). I also asked her if we owned a particular colour of sponge at home.
Yes it is weird. When she burst out laughing it got me worried for a moment. I was sitting up in my bed reading my ebook on my phone.
