As in the song 'Real Gone' by Sheryl Crow:
"Everybody's lookin' for a way to get real gone."
Does that mean something cool?
The term generally means something like absent from normal concerns or behavior in a way that's cool or outrageous in a hip way. The Dictionary of American Slang and Colloquial Expressions defines real gone as "really cool; mellow and pleasant. (See also gone.) : Man, this music is real gone." It can also mean mellowed through drugs or alcohol; the top Urban Dictionary definition says "another word for high." In some uses, the term leans more toward excited behavior; Straight from the Fridge, Dad: A Dictionary of Hipster Slang defines it as 1. Far out, wild, totally sent and 2. Insane. The term has been around for a while, as evidenced by the 1954 cartoon "Real Gone Woody." The earliest reference I could find to the term is 1941 in Google Books, in These I Like Best: The Favorite Novels and Stories of Kathleen Norris, page 50.
