Similar to there being multiple forms of clairvoyance, there are also multiple kinds of intelligence.
Those that are "clairvoyant" generally have the power to receive powerful psychic visualizations in their minds that can predict the future, see into past lives, or perceive the spirits that exist around them.
Those that are "clairaudient" dominantly have the ability to receive communication from spirits telepathically or with their ears when those around them can't hear them. (I personally have this and varying degrees of clairvoyance that I'm working on).
Those that are clair - "alient," "sentient" and "gustant" have the psychic ability to come in contact with spirits or feel vibrations using their bodies directly. Those that are clairsentient that feel vibrations. Those that are clairgustant can be able to predict the taste of something without actually tasting it. Those that are clairgustant can smell spiritual matter and energy. (We've encountered at least one or two people with this. Its quite strange for them).
Those with "claircognizance" or "intuition" have the ability to simply 'know' things about the world around them that turn out to be accurate that has no logical explanation. No lucky guess work here. Its closely tied with intuition because you're able to "sense" something at work in your environment that you can't explain you knowing. We call those with intuition 'free for alls' because you can really have any kind of intelligence yet be able to sense things without having any knowledge to them prior in your environment.
Those that are empathic can absorb and sense the emotional wave lengths of those around them and can usually tell what someone's feeling without touching them or speaking to them. Those that are empathic are usually ridiculously intuitive. (Christina has this in spades, including her brother we've come to find).
Which form of the clairs are you?
