Legilimancia

Legilimance is, in the fantastic world of Harry Potter, and in the words of Severus Snape, "to enter and know even the smallest detail of other people's thoughts", not "read" the mind "as Harry misinterprets this concept. To practice it is very important to establish eye contact with the person to whom the thought will be read; it is also necessary to formulate the spell "Legeremens".

It is mentioned for the first time in Harry Potter and the Order of the Phoenix, when Albus Dumbledore explains to Harry why he should practice and develop occlusion (the ability to hide his own thoughts).

Another expert in legeremance is Professor Severus Snape, who uses it several times to get information from Harry, and even to teach him occlumency.

Occlumency (Occlumency in the English version) is a dark branch of magic, consisting of closing the mind against Legeremancia. Access to thoughts and feelings can be prevented. The person who dominates this art is called an occlumantic. The most basic form, according to Severus Snape, involves emptying the mind of any kind of thought, in order to prevent a Legeremantan from perceiving your emotions and thoughts. It requires great willpower, and a high level of mental discipline, similar to resisting the Imperius hex.

It is not part of the common teaching at Hogwarts. Oclumanticos known: Albus Dumbledore Bellatrix Lestrange Draco Malfoy Horace Slughorn Severus Snape Lord Voldemort Barty Crouch Jr.

Despite his lack of control, Harry was able to read Snape's thoughts using the "Protego" spell.
