If you've seen the live action Cat in the Hat movie you know what they look like.

The dream:

I was in my Living Room and surrounded by Cats in Hats. One of them was a really nice female who was like the mom. The OG Cat in the Hat came in and everyone smiled. Including me. Then everyone looked at me with hungry eyes. I knew I was the main course of the family feast. I ran into the hallway and the cats cornered me. I yelled for my mom but this is a nightmare so she wasn't there. Nobody but the and the cats were. The cats then ate me.

End

Oh boy. Not talking about that horrifying thing ever again.
