I leap up and start running but I'm running too fast and too suddenly and my legs give way and then I am on the floor with my legs kicking wildly and in terror I begin to shout and bray, emitting a nasal scream screaming hep hep HEP NO NO NOOOOOOOO

it would be OK if it was a dream but it was not OK for a person just on their way to take a piss and then perhaps a drink from the water bubbler
