I'm a light sleeper. All you have to do to wake me up is open my bedroom door.

^ Doesn't light sleep mean you're feeling things and deep sleep is another word for unconscious?

I guess? I'm not an expert on that. I'm a deep sleeper. It's not easy to wake me up. The quickest way to wake me up is to tickle me...or dump cold water on my face.

Am I supposed to rephrase it then? I hope not

And I can't even think of ways I can rephrase it anyway.

I would say in between !!!!

Someone could sneeze in Africa and I'd wake up.

I could rephrase it as "Do you dream or lose consciousness?" but then I think this sounds better

The picture next to 'light sleep' I chose that one 'cause it represents what you see if you're asleep but feeling things and the one next to 'deep sleep' is because in cartoons X'd out eyes shows that someone is asleep.

I'm an expert sleeper, 10 hours a night and very few things can wake me up. Helps that I use earplugs too.
