I never felt any chakras outside the body yet. I'm working on it.
All I can say is that I read in books that there are 7 that are lower than the root and there are 7 more that are higher than the crown.
The lower 7 have served their purpose, they were active when you were going through the evolution from mineral to animal form. Human root corresponds to animal crown. (that is they are developed to that extent only, except may be for a snake and a cow). Its not so cut and dried though, its more like a continuum of activity which diminishes as we go higher in chakra scale. There can be a particular animal individual who transcends its crown and this results in a human form (birth).
There are some people who can feel them and can descend down by activating them to re-experience the animal existence. However, its a matter of common sense that this is dangerous and should not be done for fun.
Humans have the well known 7. Our crown becomes the root chakra for our next evolutionary stage, which is of a demi-god (Devas is Sanskrit). They have much finer bodies, just like an astral body or light body, and they are very much like us but superior in all respects. You can get an idea of the difference when you compare an intelligent and good-looking human to a chimp, that are just one step below us. In higher body we will go through the next 7 chakras to progress even higher.
Some people who have advanced in their spiritual practice ( must be in millions now) can feel the one above the crown. It pulsates when you attend to it or you can feel it with charged hands as a sensation. Some rare people can see it. Activity there usually means that your days as a human are almost over, and your next birth will be in a superior body in a superior world.
Please take all this info with a grain of salt. Its a great source of motivation but I have no way to prove its truth.
