Vaclav Havel, wrote letters to his wife from prison.One letter contains this uncharacteristic paragraph:
Sometimes I have the strangest feeling that I don't really want to leave this place(prison). At least not now. Here you enter a state akin to hibernation . . . sink into a kind of sweet mental lethargy and the prospect of going back into the evil world, with its constant demands that you be decisive, becomes somewhat terrifying. (Letters to Olga,p.29.)
Going to ... be decisive, ...is hibernation and 'sweet mental lethargy'.
