I recently started practicing energy manipulation or something like it. I have been using a sword to practice with where I put my energies into my blade and something strange happens. When I send the energy through my arms into my sword I feel a strange type of energy taking the form of what I can only describe as wings. So I've stopped practicing it cause it feels kinda strange. What could it mean? Also I have the ability to sense spiritual beings and energies and I have no idea how to turn it off cause I sense this stuff 24/7 and some times it will exhaust me. Also I have dreams where spiritual beings visit me and give me cryptic messages and I have no idea what to do with that.
Also I have a symbol carved on the sword that came to me in a dream once and I haven't stopped drawing it since. Could it have something to do with it?
Sometimes spirits are attached to physical objects, and sometimes the energy of a material can form a deliberate consciousness. Your sword's consciousness or subtle energy might just take that form of energy. Give respect to what and who you work with and you could have a nice working partner. This is a belief (or variant of) called Animism; physical energy has corrosponding subtle energy, and materials like stones, crystals, plants, water, and other things have spirits.
As for sensing things, you are simply new to consciously processing more energy, and until you grow used to the flow, it's going to have some side effects. Once you work more with it, you'll be able to comfortably work with the energy, as well as learn to put your subtle senses on a back burner and not have it be something going off all day. Ground, center, and shield if you'd like. Take a break from Magickal things and have intervals where you focus on purely mundane things.
For the dreams, write down what you remember in the morning (or whenever you wake up) and meditate on it later. There is a shamanic technique from the Aboriginals called Dream Reentry where you can visit your dream again while in a trance and ask questions or converse with people or objects from the dream.
I've had a similar feeling myself. I feel as if I have a pair of wings coming out of my back. Some New Age folk believe that people can be incarnated angels, but there are a lot of different possibilities I've been presented with over the years so I'm unsure. I have spoken with angels before and they said they used to be normal souls, so perhaps what we feel is simply a sign of being attuned to the Divine Consciousness (the most neutral term I could think of). I don't suppose you have a picture of that symbol you could share?
