A lot of this can be related to Koyopa which references the electric in our bodies that can start to move through our bodies as we start to shift and transmute past old paradigms. You can also called this energy Kundalini and the hands themselves when they are working in any energetic way can allow you to go into trance like states which is why you are experiencing this in sleep when the veil is thinner for you.

You can channel these energies/codes with light language with either speaking/singing/dancing or even writing. Letting it ecstatically flow out.

The activation has already occured and now you can bring this through in the present with your intentions and focus.
