Open Question: Insomnia Question!!!!!!!!!!?

Imports and exports in a band, we will use the name of our band the word insomnia. Reminds us of the immortality of sleep, but I would like to know those people are called if they have insomnia because we have five people in the band, we can call ourselves to 5 (regardless of who the person is known as insomnia), so please tell me What people have been referred to as when they sleep.
