Sathya - There are so many things I need to know to make sense of your dreams. For instance have you lost a baby in the past? What happened to you when you were two? Why are you so anxious about losing your child?
You are suffering acute anxiety, and it is made worse because it seems that you are in a strange half awake state, that can cause all manner of misconceptions.
Have you ever been lost as a child? If any of the questions I asked are true, then it could be you are experience a nightmare in which you are facing a past trauma. In which case it is worth getting support when you wake and you are still in the 2 hours of torment. You need to not suppress the motions, but fully release them is you can.
