Increased head press: Blowing your nose will cause a sudden rise in pressure in the head or "intracranial" pressure. This then, decreases circulating blood volume to the brain as well as stretches its coverings called the "meninges" leading to dizziness and headaches respectively. Or, you may just have a cold! to reduce your discomfort try either blowing your nose with mouth open or do one nostril at a time ; gently.

Hyperventillation: You are blowing too hard. Gently blow your nose. If you are having much congestion, get a neti-pot. Be sure to drink lots of liquids.

Valsalva: Often it is because people do a valsalva maneuver when they blow their nose hard. (you can google valsalva). That maneuver changes both blood pressure and intracranial pressure, and can result in dizziness.
