Magic Forums

Event since I was young I have been able to use magic in many forms such as controlling colored orbs that come from my aura and others around me when I make certain gesters like narrowing my eyes or other types of language or communication. I can communicate my will to these small orbs of rainbow colored light that only i can see and they feel like pins and needles or cottony smoke. I can also control these spirits that look like humanoid beings. I can here them to they ring to each other to communicate and I can understand them.
They appear and dissapear well certain ones do when I look at them. I don't understand what this power is i only that its called magic.
Some more examples are that I have a familiar i summoned from a spell on this site when I was twelve it was a humanoid cat creature with demon wings and a black slimy devil tail. She has been speaking to me and teaching me this power she calls magic. She wont give me her name so I named her cilia. She taught me through dreams and visions. But I don't really know what magic is. So what is the true definition of magic? Is it dominion over spirits and energy or what?
