Cover art for Parallel Universe lyrics by Red Hot Chili Peppers

It seems like its about dreaming. All the lyrics kinda say things that might go on when you are dreaming/having a nightmare.

"Christ I’m a sidewinder I’m a California king" - tossing and turning

"a solar system that fits In your eye" "You could die but you're never dead" "Take a look at the stars in your head" "Psychic changes are born in your heart"

All of those seem like dreaming or having nightmares.

Sounds cool to me.
