Two syllable synonym for "fear" and/or "adrenaline" (10 points guaranteed)?

I'm writing a song and I've been killing myself trying to think of the right word to fit in a certain spot of the first verse. I'm looking for a word that is synonymous with words like "sudden shock," "hysteria," "fear," "adrenaline," (etc.) which is no more than two syllables long. I would appreciate as many words as you can come up with. Thank you so much for any help you are willing to give and I promise I will pick a best answer.
