I’m slightly confused – spasm in fingers?

So I’ve been meditating consistently every day for the past couple weeks, but there’s one thing that keeps on occurring every single time. Around the 10-15 minute mark I begin to settle into a deep mediation, feeling at ease and peaceful, then around this time my fingers start to become very tingly which I ignore at first. I then start to feel an energy is flowing through me almost, then as a few minutes go by, all my fingers literally start moving slowly on their own and are twitching in a way to a different position, this goes on until i end up just finishing the mediation. It’s very weird.

Has anyone got any explanation or thoughts on this?
