energy entering and leaving your hands, energy work. probably charging and grounding, or you're making psi balls or something.
that whole feeling of being outside yourself, you were probably projecting without knowing it. many people, witches or not, do astral projection without knowing it while they sleep. good luck to you on your path. if i were you, i'd work on controlling your energy first. place your hands a few centimeters apart and try to form a ball with your energy, you should be able to feel it pushing against your hands, or a heat. you won't be able to physically see it, but you might see a blue glow. try to make it grow and shrink. then ground the energy by slapping the ground with your hands. try grounding if you feel you have a lot of energy inside you. you can stomp on the ground, lie on the ground, or just while meditating, visualize roots from you heading to the ground and energy going to the ground through the roots.
