The reality of it struck him as he watched his friend leave.

Then the reality of what was happening struck him like a lightning bolt between the eyes.

But then, he said, "reality finally struck home regarding my job prospects."

I guess the reality of it struck me after a while.

The reality of the situation struck him, imbedding itself all the way down to his bones.

Outside, the reality of what he had done struck him.

Then he would wake, and groan as reality struck home like a cold knife to his heart.

Prepared as they were, the reality of what had happened to Famagusta struck silence from them all.

I was 16 when reality struck me in the face.

I see that the reality has struck; they have all left.
