I seem to be shuddering every several moments, it's like what the Xians would call catching the "holy spirit" or "holy ghost" it would start with this feeling creeping up inside me or my back and rushing upwards. This started the time this xian woman from my mom church came and talked for a bit and now she is gone and I just started shuddering, I also shuddered when I was watching a show and they mentioned Satan (well they said Devil) in a bad context (like usual). Sometimes I get the shudders when I meditate but its really rare and usually has less of an on edge feeling and is more of a sensation in the spine that runs up and down my back from the base to the top of my head. But this one is just annoying, can someone explain what is happening to me?
