How can I stop waking up during my sleep paralysis stage?

Can't control this. Stage 1: light sleep (10 minutes)-slow theta waves on eeg. Stage 2: 20 min of rapid rhymic brain wave activity (sleep spindles). Stage 3: deep slow brain waves (delta) emerge, transitioning from light to stage 4: delta wav, : deep, 30 minutes. At end this period maybe when sleepwalk or bed wet. Stage 5: dreaming, rem sleep: this is the muscle paralysis and increased brain activity period, paradox.
