I would say the language you are speaking is imparting a feeling of empowerment, no?
I used to experience that if I spoke pseudo-latin.
It has a lot less to do with magic and a lot more to do with psychology. Your soul is getting into a groove, feeling something "magic-ish" going on.
The energy is real. Don't have any shame about this.
What I would suggest, though, is focusing on harnessing that empowering vibe in ways that are more direct, such as making that feeling directly. Flexing your energetic muscles by bringing on the feeling without the speech.
The spirits in the spirit world probably like to say "no, it IS a real magical language", but that would only be true very very technically, because you feeling it is magical is really all that is making it magical. The spirits are just like that.
From there, you can start to feel what your soul feels like, and controlling energy. Start by working with the chakras or something basic to get used to it first. Get to where you can open them by just "doing" it. Practice sending down a grounding chord from your root chakra.
That may all be in the future.
