What colour is your couch, Gracey or anyone else?

Last night when i first got into bed, i glimpsed a blue light with a flash of aqua green.
Then i saw part of a couch.
It was either black or charcoal grey with a white design on it.
The arms were as high as the back of the couch and i believe the couch had a slight rise to the back of it in the middle.

Where that came from is beyond me, but maybe one of the others here has a couch of the colour?

Thanks for any comments
