Dream of mother, woke up, chased

I watched comfortably sitting on a rock, tall yellow grass, green shrubs, tall deep rooted and thick trees, as two tiger cubs chased playfully and drew blood from a goat. one cub would run to a hide in the green shrubs and they other, as if tagged in a Big Time wrestling match, would come out from the hidden spot to playfully, yet without remorse, plant its long teeth into the tiny goat. both the cubs were dripping with more blood than the tiny goat could have produced, I thought. I wondered where the mother was unafraid as I watched perched on the rock. I woke up either because I need to evacuate my kidney or because I didn't want to watch the goat killed.
