Rejuvenation
Rejuvenation can be described as feelings of mild to extreme cognitive refreshment which can last anywhere from several hours to many years and are often felt after positive experiences with certain hallucinogens. These feelings of rejuvenation can potentially include a sustained sense of general heightened mental clarity, increased emotional stability, calmness along side of specific subjective effect components such as mindfulness, increased motivation, cultural filter suppression and increased focus.
At its highest level, feelings of rejuvenation can become so intense that they manifest as the profound and overwhelming sensation of being "reborn" anew. This feeling can last anywhere from weeks to a lifetime after the experience itself.
