psychic (サイキック）
I am a psychic. 私は超能力者です。
I have psychic abilities. 自分には超能力があります。
ちなみに「エスパー」はどこからきたかというと、ESP (Extra Sensory Perception：感覚外[知覚](https://eikaiwa.dmm.com/uknow/questions/90444/)または超感覚的知覚)という、あるアメリカの大学が[超能力](https://eikaiwa.dmm.com/uknow/questions/97052/)を研究しようとデザインした学問につけられた名称に、「人・者」の意味のerをつけてESPer 「エスパー」となったという説が一般的のようです。
案外かけ離れたところから来た言葉という訳ではないんですね。
Psychicが一番使われる表現です。人の考えてる事が分かったり、人の過去が見えたり未来を予言出来たりする人です。
Mysticだと少しスピリチュアルまたは宗教的なニュアンスが加わります。北米のインディアン達のシャーマンなどを連想させる言葉です。
A person with supernatural powers＝ 超能力を持つ人
超能力はsupernatural powersです。最初の二つだと単語なので先に挙げましたが、この言い方でも勿論伝わります。

Usually, a person with supernatural abilities would be someone who can see into the future or see spirits/ghosts.
You can say "physic" or "clairvoyant" for someone who can predict the future.
For someone who speaks and sees ghosts, you'd say "medium."
There are many different words that can be used to describe people that have/has supernatural powers, above are a few and here are some more:
"Clairvoyant"
"Palm Reader" they use the palm of your hand to see the future
"Oracle" is believed to see and know everything
"psychic/Fortune teller" This is a person who can see into the future and tell what is going to happen.
"Mystic" If someone is described as mystic then they have something to do with magic and illusions.
"Superhero" These are people who have some sort of power like flying or super strength.
Well, someone may claim to have supernatural ability by being able to predict the future. A 'fortune teller' may look into a crystal ball, or study cards to predict someone's destiny. A 'medium' may claim to be able to put people in touch with their deceased loved ones. On the other hand, a superhero such as Spiderman has other outstanding skills such as being able to fly, or tremendous strength to stop a train.
A fortune-teller = a person who has the supposed ability to tell a person's fortune (e.g. how lucky they will be or how successful they will be)
A clairvoyant is a person claiming to have clairvoyance which is the supposed ability of looking into the future and perceiving events in the future. They seem to have a sixth sense of clairvoyance, telepathy, intuition or extra-sensory perception (ESP). A psychic is a person who appears to be clairvoyant or telepathic.
