Dreams are the stuff?

I had a horrible dream around 4am.

For some reason, D, Austin (nephew) and A were having a bath together at my house. I was in my room doing whatever, and then I noticed it was quieter in there. I went to go check on them and A was completely submerged and starting to slip down more. I grabbed him and pulled him out and water poured out of his mouth and he was choking. He wasn't crying but was ok and in the dream I was so upset that all I could do was stand there in the tub shaking, crying, and saying I'm so angry. It was like the older boys got caught up in playing and didn't notice him going under the water, because they looked just as surprised and worried as I did.

Really weird. I have no idea where it came from.
