Terrible Nightmare

I just had the most vivid dream. I was pregnant still didn't know what I was having. Someone had taken me and my son. They were distracting me and then I hear him scream for me. All I see is a hand pulling him away and I chase them and keeping chasing them through the house and all these rooms but I can't catch up. I woke up before I could save him. In tears and out of breath. It was so scary. :(
