In brief: Have it checked

If it happened only once may be nothing.
But if this happens repeatedly you should get an evaluation. It could be vasovagal episode, heart rhythm problem, medication effects, dehydration , anemia or any number of things.

In brief: Many possibilities

The feeling of faintness is a sign that not enough fuel is getting to the brain.
There are many potential causes, a sudden drop in blood pressure for a variety of reasons, dehydration, low blood sugar, anxiety and others. The likelihood of different causes vary by age and the setting in which the feeling occurs. You should see you regular doctor to discuss this further.
