Robomatic's idea makes a lot of sense.

There are different neural pathways to brain centers triggering (automatic) action and to centers triggering conscious perception. Experiments with brain damaged persons having 'blindsight' also point to such explanations.

Since there is no conscious perception of what has triggered (or hindered) an action people experiencing such an event often use expressions like "feeling" "hunch", "sixth sense" to describe their perfectly normal though perhaps not common experience.
