Yes , people CAN faint from high blood pressure as it is very dangerous.

Fainting is a temporary loss of consciousness that is spontaneously recovered after only a brief period of time. People faint because of a lack of blood flow and decreased oxygen to the brain.People most often faint as the result of an abnormal circulatory reflex. Some people faint at the sight of blood, in a crowded room, or even from excessive coughing. This is referred to assituational fainting and might affect a person repeatedly, but only in a very specific situation.People may also faint when standing up after lying down. Referred to as postural fainting, this results from a decreased flow of blood to the brain, usually as the result of a drop in blood pressure. Postural fainting can occur after significant blood loss, dehydration, or a change in cardiovascular medication, or as a side effect to other medications. Certain medical conditions, such as heart disease, diabetes, and migraine headaches, can also serve as a catalyst for fainting.Most people who faint experience symptoms beforehand. These symptoms may include lightheadedness, blurred or "spotty" vision, dizziness, and weakness. People who observe someone about to faint might notice paleness, sweating, and dilation of the pupils. In most situations, people who faint regain consciousness within a moment or two.
