I once channeled a light green/white aura around me, which shaped itself into two blades at the end of my arms, and I could also generate shields made out of the same aura, which I used to protect myself and the two DCs I was with. I think I tried to do something else, but it didn't work.

This was all in a regular dream, but it was quite vivid so I'm counting it as my internal power, so yeah.
