Even those with cast-iron stomachs have many issues with food that are rooted in their constant hunger for energy. Contrary to the image of the vampire as thin, many real vampires are troubled by obesity because of a hunger that makes them food addicts, and a system that is sluggish in processing physical food. They are also sometimes troubled by other substance addictions for the same reasons, but since their systems are tuned to pranic energy more than to processing physical substance, they may not be as sensitive to drugs and alcohol as an ordinary person would be. Emotionally and physically, vampires are unpredictable, moody, temperamental and overwhelming. The major distinguishing characteristic of real vampires as opposed to ordinary people who share those qualities is the vampire's intensity.
Vampires are extremely intense people.
A vampire's emotions are deep, fervent, and powerful, and she usually displays great psychic ability and has uncontrolled magickal and psychic experiences. For this reason, some vampires develop a pattern of being aggressively confrontational, or of constantly antagonizing people with whom they have relationships. Once a vampire overloads on energy, she reverses her behavior patterns. She may become morose, silent, withdrawn and introverted. Some vampires become maniacally cheerful when they are satiated, but even their good moods seem to annoy others, and it is more typical for vampires to be infamous as wet blankets.
