Can resistance come in short intense bursts?

[Shannon]

I am listening to to a particular 4G sub...
Sometimes when I sleep I get a sudden shock in my body u know like.. Hypnic jerk and its really strong..is this some kind of fear being released? Anyone experienced this?

You have that experience every time you fall asleep, to some degree. The only difference is that you are more conscious than usual when it happens recently. It happens to everyone as they fall asleep, though.
