I have the same experience. However, I usually "slip" and fall headfirst onto the asphalt. Well, that's when I wake up.
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
