People of this personality type are essentially concerned that their lives be an exciting adventure. Sevens are future oriented, restless people who are generally convinced that something better is just around the corner. They are quick thinkers who have a great deal of energy and who make lots of plans. They tend to be extroverted, multi-talented, creative and open minded. They are enthusiasts who enjoy the pleasures of the senses and who don't believe in any form of self-denial.
Sevens are practical people who have multiple skills. They know how to network and to promote themselves and their interests. They often have an entrepreneurial spirit and are able to convey their enthusiasm to those with whom they come in contact. When they are able to focus their talents, they are often highly successful. Focusing does not always come easily for Sevens, however. Their tendency to believe that something better awaits them, makes them reluctant to narrow down their options or to pursue their aims with true devotion.
The central problem for Sevens is that their pursuit of pleasure is compulsive. Sevens are fear types who are specifically afraid of the power of negative states of mind. These they avoid by seeking distractions in the external environment: by multi-tasking, by keeping their options open, by engaging in stimulation seeking of all kinds. For this reason, Sevens are more prone than most to addictions of all sorts, whether it be to shopping, gambling, drugs or whatever.
Sevens usually have a high opinion of themselves and their talents; they tend to focus on their strengths and virtues and to downplay their flaws and vices. They are often a bit self-centered which manifests in an unfounded feeling of entitlement. As Sevens don't want to confront their own darker emotions, they also have difficulty acknowledging the pain that others experience, so that they sometimes have a hard time seeing the reality of other people. The extent of the Seven's flight from negative emotions is really a measure of the Seven's mental health; the more that the Seven flees from them, the more their strength grows and the more likely they are to erupt into consciousness in the form of an anxiety disorder or a severe depressive episode.
Instinctual variants
The instinctual variants of the enneagram, the self-preservation, sexual and social instincts.
In addition to the Enneagram type, people are also considered to be one of three instinctual variants (also called subtypes). The self-preservation instinct (dealing with oneself), the sexual (dealing with another person) and the social instinct (dealing with a group) can be most pronounced.
People of the sexual variant are very much interested in one to one contacts. They are looking for intimacy and this may show in sexuality, though not necessarily. Being in a relationship is very important to them. They are the most passionate of the subtypes, being temperamental and having more energy. They have less of a problem with getting into a fight and care less about rules and responsibility.
They had a Chakra test too...

Too many explainations here,
Let's just stick to my over-active and under-active one.
Over-active : Third Eye
The third eye chakra is about insight and visualisation. When open, you have a good intuition. You may tend to fantasize.
If it is overactive, you may live in a world of fantasy too much. In excessive cases, hallucinations are possible
If underactive, you are not good at thinking for yourself and may tend to rrely on authorities. You have rigid thinkings and confuses easily.
Under-active : Root
The root chakra is about being physically there and feeling at home in situations. If open, you feel grounded, stable and secure. You dn't unnecessarily distrust people. You feel present in the here and connected to your physical body.
If over-active, you may be materialistic and greedy. You will probably be obsessed with being secure and resist change.
If underactive, you tend to be fearful and nervous. You easily feel unwelcomed too
Sounds scarily true...
Haha...
Maybe you can have a go at it?
