Bathtub Dive

I am standing on the edge of the bathtub. The bathtub is filled with water up to the edge. I lean over the edge and submerge my head deep into the water. I thoroughly wet my hair. After a few dives, I start with shampooing. However, when I submerge myself underwater to rinse out the shampoo, something invisible is trying to push me deeper and longer underwater. You struggle repeatedly to escape and manage to get away. After that, I do the second shampoo and conditioner. I face several crises, but I safely rinse my hair at the end and manage to escape.
