It might be a condition if it happened all the time. Not just twice. Stop eating hot dogs. If it stops, you will be healthier anyway. If you must have a hot dog, there are great vegetarian ones. If you knew what went into a hot dog, that would make you sick anyway. Again, if you stop eating hot dogs and it never happens again, problem solved.
There is something called silent migraines, which can have a lot of the symptoms you describe. I don't know if that's what you had, but maybe something in the hot dogs triggered them. It might be that particular brand of hot dog, and a certain ingredient in them, or just hot dogs in general - they have a lot of nitrates, which is a preservative known to trigger migraines, and tons of sodium, which also can.
It's basically a migraine without the pain.
