The Wayward Sun

Largely unfazed by the fact that one of them has just killed their best friend, Wren and the suddenly sober Chaz leave their overturned jeep on the road and wander off into the desert, walking at a snail's pace and never checking google maps despite their phones' phenomenal battery life and reception. Wren hallucinates an exotic dancer and reaper-like phantom, which are creepy the first couple of times out of their zillion reappearances. Later, a stoner cactus preaches existentialism.
