First, dont open your eyes!

My best advice is to breathe and relax through it, and affirm that it can in no way hurt you, then enjoy the experience that follows!

If you really want to break SP, then dont try and force yourself to move. You cant move, and it will only feedback into more fear. The one thing you can control during SP is your BREATHING. Completely alter your breathing pattern to say very deep breaths. This breaks SP quickly.
