The `We Made You` rapper - who has famously battled an addiction to prescription drugs - often thinksabout his own passing when he is in bed but admits it "creeps" him out.
He said: "Do I think about my own death? Yeah, I do. A lot. I think about it a lot. I try not to think about it but I do and it creeps me the f**k out! When I lay in bed at night is when I think about it the most."
Recalling a time when he was hospitalised at the height of his drug addiction, Eminem added to Vibe magazine: "It creeps me out because they say that if I got to the hospital two hours later then I would be gone. I think about that a lot."
The rapper - real name Marshall Mathers - also revealed how easy it was for him to obtain illegal prescriptions from doctors overawed by his celebrity status.
The hip-hop star - who checked into a rehabilitation centre in 2005 to be treated for an addiction to prescription pills - explained: "It`s one of those things where you`re famous, doctors will kiss you`re a*s because they love the celebrity. `Oh, I can call up Eminem and get him on the phone right now. Oh, hi Marshall, how are you doing? Do you need that prescription?`
"There are doctors that will give you certain things just because of who you are."
Eminem also spoke of his shock at his `8 Mile` co-star Brittany Murphy`s death in December, admitting he thinks there is an epidemic of tragedy currently sweeping Hollywood.
He said: "It was crazy. It`s crazy. It`s crazy because at one point we were very close and she was a really good person. It`s crazy when you see things not just with her but just all these things that are happening in Hollywood with people in music, with people in acting, famous people. Famous people are overdosing at alarming rates and - that almost sounded like a commercial. Wow."
