Sounds like a form of migraine.
thankyou for your response but that was no way any kind of migraine it is so hard to exsplain i dont understand what happened i want to but i dont know i had no pain in my head but it felt like the wind was knocked out of me too but it lasted for a few minutes
If not headache then the only alternative would be a sudden drop or increase in blood pressure, to the levels where you could lose consciousness. Are you drinking enough fluids?
