It is not normal to black out. When a "black-out" occurs, it is due to some kind of problem with the body, and generally results from a sudden decrease in the amount of oxygen flow to the brain. Black-outs can occur due to low blood pressure. This low blood pressure, in turn, can be due to a problem with the pumping ability of the heart, a sudden loss of muscular tone in the arteries, blood loss, or even a psychological shock ("fainting"). Black-outs can also occur due to excessive toxic exposure (drinking too much), trauma to the brain (getting "knocked out"), or a sudden decrease in oxygen (altitude sickness).
