Throwing up in the bathtub

I was in some bathroom - looked like a new bathroom/new house. Big white tub, dark wooden walls. Started to fill up the tub - it filled up within 3-5 seconds and I turned it off right before it was about to spill over. I was standing over one side, and started throwing up. It looked like pho noodles, except 3 bowlfuls of it. I don't remember if it was actually noodles or worms or both. I poked it to move it around, then the water started turning into blood. There was a handle near the bathtub that looked like it would "flush" the water. I tried to press it gently but nothing moved.
