Somnodrag /ˌsɔəm.nə.ˈdra�?g̥/ happens when you stay up all night - not because you drank too much and stayed up vomiting, or you had to watch all that tv season box set - but because some weird mood came over you and you ended up having an all-night, meandering, philosophical conversation; you look up, and it's morning.
Knackered, you intend to go to bed, sleep it off, get back into the diurnal necessity of normal life after a good old rest. But someone chooses to somnodrag (v) you out of bed - usually for something stupid. You spend the day experiencing somnodrag (n) - that absolutely tired fuzzy feeling when the world is a secondary concern. Make sure that you don't get dragged to a public space, or you could become a zimbtrovert.
