ugly sleep 

Acquired during the deepest stages of a much-needed restful night; when you're so sleep, you sleep through alarms, often with mouth ajar, face planted against the sheets.

I tried to wake you up in time for the bus but you were in a deep ugly sleep. I couldn't bring myself to interrupt

my girlfriend attempted a beauty sleep yesterday but took an ugly sleep instead, she woke up looking like a confused killer whale
