It was a What?

It hovered in the air above me. Across the room, its yellowish tendrils snaked towards me. It swam in the space between us, menacingly silent like a deadly jellyfish.

"What is that?"

In the dim light, I struggled to focus on its spiky body as it inched ever closer.

"What the fuck is that??"

It jerked forward. I jerked upright.

"Oh, damn!!"

My spouse, confused, looked over at me.

"What are you talking about??"

The words come out haltingly. "A...sand spider...is flying towards me."

He chuckles. "Go back to sleep, honey."

After a moment of thought, "Oh. OK."
