It happens to me probably once a week or so. It is a good exercise in calming thoughts down and being rational about what is going on. I usually just focus on staying calm and trying to move one finger or one toe patiently until it does, and the second I can move one digit a bit my whole body snaps online. Sleep paralysis, being extremely stoned, and having my contacts fall out at inconvenient times (I am pretty blind) have all been great exercises in suppressing mounting panic haha.
