Startle reflex

Do any other mommies have babies that literally scare the living daylights out of themselves when they startle themselves 😢 my daughter does the baby thing of flinging her hands up but it’s followed by a look of terror on her face and the most blood curdling scream. It’s heartbreaking to see and if I can’t get to her in time Ie in the shower she screams like someone is hurting her. I’m worried something is wrong
