Just Trying To Figure Out What Happened At Lunch Today

Just trying to figure out what happened at lunch today while out with a friend. we were in the middle of eating and all of the sudden I felt like I was in a dream state where it wasnt real and things were in slow motion then as it continued, I felt weird sensation throughout my body, not pain or numb or weak but just like a surge or something then as it was subsiding I was shaky. Never had pain or weakness or dizziness or anything just felt like I might faint or pass out.
