I don't know if it supposed to happen to famous people only, but I've heard this too When I worked my first job as an RN in a nursing home. I worked graveyard shift for 3 yrs. I did have residents die on my shift, not that many tho. But it seemed it went in 3's when people were dying at the nursing home.
I can't remember what yr, 2002 or 2003, all these famous celebs were dying like flies, this was the whole yr. Maybe the yr. John Ritter died- it seemed every other day someone famous ie musician, actor, etc was dying.
