There's a Snake in My Bed

I woke up in the middle of the night to find my husband holding the covers of the bed up in the air while he looked underneath. I had no idea what he was doing but soon got concerned when he started talking. Here's how the conversation went:

Him: "What is that?"
Me: "What is it?"
Him: "What is this?"
Me: ...speaking in a panic, "What's under there?" (now thinking that there is a bug or snake in our bed)
Him: ...still holding the sheets up, "This is carbon wire!"
Me: "What?"

I soon realized there was nothing to fear. No spiders, bugs or snakes in the bed. After hearing my husband talk about carbon wire I knew it was safe to roll over and go back to bed.
