Weird symptoms? I almost felt like I was having a stroke.?

Ok, so I am 18, female 4'11" very healthy, 98ibs. I am vegan and health conscience- I always grown my own food or eat organic/locally grown food and almost never get sick. However, today for about 5 minutes I felt incredibly strange, I couldn't speak well, collect my thoughts or pay attention. I felt like I was in a daze, very dizzy (I have never touched alcohol/ drugs and I don't know people who do), I could barely swallow my dinner and I couldn't even text a simple message. Any suggestions as to what the hay happened? I feel completely normal now, I have no idea what happened.
