As some have eluded to, could it harken back to our 'cave man' days? Our ancestors slept on the ground, now we are raised until we have a gap
underneath us. An unprotected space? Comming from behind? I read that the reason rocking babies puts them to sleep is because it mimmicks the way our
ancestors were migratory, and the rocking simulates the walking motion. just as an example of our programming.
