Dazed

✦     The creature doesn't get its normal complement of actions on its turn; it can take either a standard, a move, or a minor action. The creature can still take free actions.
✦     The creature can't take immediate actions or opportunity actions.
✦     The creature grants combat advantage.
✦     The creature can't flank.

The dazed condition is a common way of representing a general state of stupor. Dazed creatures don't act as quickly as normal or respond to danger as readily. A creature might be dazed because it took a hard blow to the head, a spell assaulted its mind, or a prayer called forth a clap of thunder around it.
