And I’m not sure why I’m infatuated with death,
My imagination is surely an aggravation of threats…
Maybe cause I’m a dreamer, and sleep is the cousin of death,
Really stuck in the scheme of wondering when I’mma rest.

Kendrick Lamar, “Sing About Me, I’m Dying of Thirst," good kid, m.A.A.d city, 2012. More Kendrick Lamar quotes…

Never we sleep, a thug doesn’t rest,
Cause a wise man said: it was a cousin of death.

Big Pun, “Who Is a Thug,” from Whiteboys soundtrack, 1999

Death is the cousin of sleep,
Just close your eyes, count sheep and breathe deep.
Think about the sound of relief that surrounds you,
You were already gone before I found you.

Slug, “Bleed Slow,” from Atmosphere’s Godlovesugly, 2002

They say sleep is the cousin of death, guess we related…
Cause I’m the most slept on, and the most hated.

The Game, “Sleep When I’m Gone,” from DJ Khaled’s We the Best Forever, 2011

If sleep is the cousin of death, then death is the cousin of sadness;
Murder’s the cousin of madness, love is the cousin of that bitch.

Ill Bill, “Secrets Worth Dying For,” from DJ Muggs & Ill Bill’s Kill Devil Hills, 2010

I never sleep, ‘cause sleep is the cousin of death.

Nas, “N.Y. State of Mind,” Illmatic, 1994
