Why do i dream that my alarm clock is part of my dream in the morning and i sleep through it because i think it is a dream this happens every day?

I would guess that you're not getting enough sleep. As a mom, I would say you're probably going to sleep too late and then you're in a deep sleep cycle when your alarm goes off so your brain doesn't recognize the alarm.

Try going to bed 1 hour earlier FOR ONE WEEK and see if you're beyond your deep sleep cycle when the alarm goes off. If so, you'll hear it go off and actually wake up.
