A girl often sends me short messages and tells me every time she sleeps. What does that mean?

First, she is just bored, hoping to find someone to chat with before going to bed, and thinks you are the right person to chat with.

Second, she may be interested in you. When you reply to her message, there will be a topic slowly, and maybe there will be further development.

Third, she sent it to you on her own initiative, but you should pay attention to whether your daily behavior has caused misunderstanding and made people think that you like her, so she sent you a message.

Fourth, if you have feelings for others, you should reply to the message. If you don't, just politely refuse. Avoid sending messages to you every night, because sending messages at night is an ambiguous time. Many boyfriends and girlfriends use the pursuit stage to launch an offensive before going to bed at night.
