not sadness is an emotion that often comes back after a vision "nostalgic" for something. A person is often melancholic romantic, or of romantic ideals.
Typical of the attitude is a sad and melancholy nostalgic or in some cases depressed and devoid of desire to do.
could be defined as the desire, deep in his soul, a thing or a love that you never had, but he feels sorely missed. Melancholy may be manifested in facial expression, a feeling of sadness that can last a lifetime. (From wikipedia)
Melancholy has waves like the sea makes you go back and then gently cradle youmelancholy is like a slow dance in the silence you can squeeze and feel it all inside
you feel close and even distant is standing still
travel is to live other lives
is feeling in the air inside airplanes ships
lit on the trains that go see
has the warm glow of a sunset red and
one day hurt that will not die never seems
Happiness, it seems kind of soul that goes
the dream that blends the reality
can exchange it for sadness but 'only the soul who knows that the pain will
(from melancholy Luca Carboni)
