Scary Sleep Paralysis!?

Alright, so I suffer from sleep paralysis. The first time I ever experienced it, I must have been 12 or 13 years old. Back then, they weren't so bad and I seldom experienced them. Throughout the years, they've become more and more frequent. I'd say this year alone, I've been getting them 4-6 times a month. Sometimes, I'll have a bad week and get it 2 or 3 days in a row. Just last night, I hallucinated sirens roaring outside my room, and felt a hand grab mine. I tried to pry it off using my other free hand and then felt another hand pull it away. It was lucid and terribly frightening. I feel like I'm going crazy! Before, I never had tactile hallucinations, only visual and auditory... I'm scaring myself now. Anyone else experience this? And what helped? THANKS!
