Hi dilermando
Travelling in a
fried-out Kombi
On a hippie trail, head full of
zombie
As a Brit, but not a teacher, I would understand "fried-out" to be equivalent to "burnt-out", as in a burnt-out engine - one liable to "die" at any moment.
A Zombie is a soul-less body - see Answers.com:
zombie: Definition from Answers.com
I would read: "head full of Zombie" as meaning being in a mindless state (probably drug-induced, as in the "flower-power/hippie" days of the 1960's).
Hope this helps
Regards
