Dysania is, apparently, the state of finding it hard to get out of bed in the morning. I assume that this means that you are drowsy and dreamy, rather than that you still sleep in a cot. The OED doesn't list the word, but it does appear in a medical dictionary of 1958.
This is a terrible condition, especially when combined with uhtceare, an Anglo-Saxon word that meant sorrow before dawn. It also goes rather well with hypnopompic, and myoclonic jerks. In fact, the subject seems to occupy me more than is healthy.
A nap, I think.
And why would you?
