Hands vibrating ?

I started my journey in November 2020, and I’m at the step where I felt some P-waves but I keep experimenting. At the end of my last sessions, I suddently felt like if my hands were vibrating. I would say it happend rather suddently because I don’t notice it sooner .It doesn’t feel the same as a lack of blood in a member, but it looks like enough to affraid me, and it’s the same intensity.

I never saw anything about that in this subreddit, so I wonder if anyone experienced that sensation before.

(sorry if my english isn’t perfect)
