Cover art for High On A Riverbed lyrics by Toad the Wet Sprocket

This song seems to be about those moments in an otherwise sad, frustrating, and seemingly pointless life when you suddenly stop and realize that it's going to be ok.

" you suddenly stop and realize that it's going to be ok"

Because you're stoned. That's the only way to be high on a riverbed - riverbeds are always the low point in the terrain.
