She claimed to have extrasensory perception, able to see things that others couldn't.

"Some of the instances of a religion are called telepathy, extrasensory perception, or miracles."

Extrasensory refers to something which falls outside the normal range of human senses. In the case of ESP (extrasensory perception), it just means that someone has super sensitive perceptions like telepathy, clairvoyance or precognition.

Extrasensory. Zen Headbutt is a physical type move so therefore it is subject to Pokémon that have Static, Rough Skin, etc, but Extrasensory is special type move. They have the same power so that doesn't mean anything. Also, Zen Headbutt has an accuracy of 90 while Extrasensory has an accuracy of 100. And they both may cause flinching. So therefore extrasensory is better.
