Idk why this keeps happening im scared

3 or 4 times in my kids loves ive been dead asleep and woken up in a panic trying to do mouth to mouth resuscitation on my kids. Im asleep but i feel like they are unconscious and it takes me 2 seconds to realize im asleep and then i stop. My kids sleep next to me. Idk why this is happening i have a little anxiety but no signs of ppd. Has this happening to anyone else or advice?
