From a dream:

Washed gray skies fill the large panes; she notes the unfamiliar color as she enters the room. The broad portal pervades the wall from floor to ceiling. Weathered walnut confronts the cool murky canvas it frames. She sees the window is open a few inches from the bottom. Standing before it, meeting her ghost’s eyes, she stares through to the neighboring roofs. It looks cold, and she shivers; the moment delays a message from spirit to flesh. Impulsively, she pushes the window down from the lower pane’s top sash, but it doesn’t completely close. As she steps back, beginning to turn toward the doorway, her eyes remain tethered to the window. She studies the condition and, returning to the frame, squats down to the bottom sill. With full weight, she pushes it to shut and bounces up to lock it at the junction.

Now she could leave the room.
