From home, a cabin is a small wooden structure.

So what could it mean to have cabin fever?

Jonathan, I really need to get out of this house.

Sounds like you've got cabin fever.

Maybe you should take a walk.

I've taken five walks today, and it's not even 10 AM.

I need to see my friends in person in a restaurant.

When you are stuck indoors because of bad weather and illness or some other reason, you may start to feel bored and even trapped.

This feeling can be called cabin fever, and that's English in a minute, okay?
