It's definately not wrong to want nothing... but it is kinda sad. It just shows how hurt the person really is, that life has come to the point of wanting nothing but existence for fear of receiving anything that would symbolize life. I think that someone who wants nothing is at the end of the line, but for some reason still holding on to it... maybe hoping that tomorrow might be better? The absense of dreams and hopes are there because the persons life has been filled with fear and shame IMO.
