Dream About Childhood Nightmare

I woke up from a nightmare, I was back home, it appeared that the adults where not home, there were a couple of childhood children around, my fathers business partners children in fact, we were in their home.

He kept hitting and lashing me with the belt wildly in anger all I could do was whimper and cry trying protect myself from the lashings striking my face or head. He was enraged? I woke up suddenly while trying to protect my self by guarding my face body and head. He was so angry…
