Another possibility is some seizure disorder (like epilepsy).
When I worked 911 in Los Angeles County, as long as it wasn't the patient's first seizure and they have a known disorder, they could refuse transport to the ER. The seizure can last a couple of minutes, using up a lot of energy and decreasing breathing. The last phase of the seizure is the postictal state in which the patient can be unconscious, severely disoriented, lethargic, combative, etc. During the entire thing all you have to do is make sure they don't hurt themselves (in LA, we never worried about a little thing as a tongue. We're talking head injury) and give them some oxygen to maybe make up for decreased ventilations.
During that postictal state, you just wait it out, and it can take several minutes. Eventually, blood sugar, alertness, orientation, etc. all come back to perfectly normal. As long as there's no physical injury, no need for ER.
Speculation, of course, but if the seize time plus post-seizure disorientation got exaggerated to 35 min unconscious (as was always the case from bystanders on those 911 calls), this was a simple seizure, and it's, as clayton put it, perfectly logical to continue onward. The ER would have glanced at her then sent her home.
