gotta hate that kind of 'blur'

This happened yesterday.

My mom woke me up from my short nap to have my meal. I stood up went to the kitchen and was about to get a plate of champorado for lunch, I felt dizzy and my eyesight was dim and blurry, everything turned almost black. I grabbed my plate of champorado, sat on the dining chair. Got on a grip on myself.. I prayed silently.

Could this be something serious or am I just being PARANOID?
