Again, I'm probably not the person to help you write a song, but when I think of it in terms of how you described it then the first musical performers of the Pchychedellic style that come to mind would be Jim Morrison and the Doors. "Riders on the storm" would be a perfect example. In fact, just listening to any sixties Woodstock era performers like Jefferson Airplane, Grateful Dead, Bob Dylan, even Hendrix and Pink Floyd would certainly give you some ideas about what your describing, but like Snojones stated trying to incorporate them into a country groove is gonna be your biggest challenge. Good Luck.
