The main psychological effects of MDMA:
  1 - "Entactogenesis" ("internal touch") is an all-encompassing feeling that everything is in order and everything is good in the world and with you.  It is often described as "peace", "magic" or "just happiness."  In addition, ordinary, everyday things can turn out to be unusually beautiful or interesting.
  2 - "Empathogenesis" is a feeling of emotional closeness and love for others (and for oneself), combined with the destruction of barriers in personal communication.  Usually, with the influence of MDMA, it becomes much easier to talk with people, and possible obstacles that inhibit communication, such as shyness or awkwardness, are very easy to forget.  Empathogenesis is one of the reasons that MDMA is known as the “hug drug” - increasing emotional closeness makes intimate relationships very exciting.
