I was introduced to his word from His Royal Foxiness only yesterday. It is apparently the state of finding it difficult to get up in the morning. Heh. If this is a real disorder then I and just about everyone I know “suffers” from it.
There may also be an element of alcohol involved, as the Urban Dictionary further defines “dysania” as the “state of finding it hard to get out of bed in the morning after a hangover.”
Someone, somewhere, just made it up.
