I've had those in the past usually accompanied by a feeling like I was on a chair-o-plane ride so that for a minute it's as if my stomach drops away. I mentioned them to my GP who was concerned that it could be a partial-seizure. Tests came back ok but, now and again, I still get those feelings. I don't get wiped out by them though although I remember it was one of the questions the GP asked me at the time. This is from an American epilepsy site
"Simple Partial Seizures
During a simple partial seizure, formerly known as a focal seizure, the individual remains aware. A simple partial seizure may involve sensory, motor, psychic, or autonomic symptoms. These symptoms result in the person experiencing an unusual sensation, feeling or movement called an aura. The aura may be a distortion in sight, sound, or smell where a person sees, hears, smells things that are not there. It may also be a sudden uncontrollable jerky movement of one area of the body, such as the arm, leg or face. A person may experience a sudden overwhelming emotion, such as joy, sadness, fear or anger. Others may experience stomach upset, dizziness, a shiver, a tingling or burning sensation, pallor or flushing. Occasionally there will be the experience of déjà vu during which a person has the sensation of having experienced something before.
The seizure usually begins suddenly and lasts seconds to minutes. An aura is a simple partial seizure that may occur alone or may progress to a complex partial seizure or a generalized seizure. If the aura indicates the onset of a complex partial seizure or generalized seizure, it can sometimes be used as a warning signal to allow a person to take the necessary precautions to avoid injury."
