Hard to explain

I don't even know how to start. You know that feeling: When you get really close to someone, see them everyday, laugh with them - and then suddenly. That person is gone. Just like that? And then you spend the whole day thinking about them, trying to explain yourself that they're gone, but somehow you just won't understand it? Because you don't want to. - And then , at night.. that person calls you. And you talk. And for a second it feels like they're sitting right next to you. And everything that happened today was just a dream.. But you know it's wasn't.
