Vibe is the aura a person possess. The kind of vibes that a person emanates depends on his feelings. Every feeling has a frequency or energy. If you feel good, happy or comfortable while meeting someone you say that the person emanates positive vibes.
In Latin and Ancient Greek, aura means wind, breeze or breath. It was used in Middle English to mean gentle breeze. By the end of the 19th century, the word was used in some spiritualist circles to describe a speculated subtle emanation around the body. History
