My daughter was warming up with the band for a parade she ran from her place and line and fainted. She has no memory of this - ideas?

Dehydration?

Epilepsy?

Too much excitement?

Thanks! The fainting part could have been dehydration. I know its not excitement. I'll research epilepsy - no previous episodes. The part that really has me concerned is running from her place in line and having little memory of it. She said it felt like she was dreaming...
