You really don't get that line?
It's similar to death.

I don't think death is similar to sleep, except for the fact that most of our functions are shut down and probably the position? And if it's some american or canadian famous quote that has some meaning to you guys, no, I don't get it.

It really doesn't matter where the quote originated (but it was in a rap song by Nas), because it's universal. You stated why it's similar to death. Haven't you ever heard another quote, "I'll sleep when I'm dead" or people referring to death as eternal slumber? It's all over the place.

yeah yeah I guess you're right

No I really dont know what you mean because I never make mistakes.

I'm perfect in every way and everything I do is perfect too !!!
