Um, interesting. Emotions do tend to be greatly intensified in dreams, for whatever reasons.
You're not the only one who had a dream like that. Once I dreamt I was with this alien man who kinda looked like Dr Manhattan, he was like a father to me in the dream and we deeply cared about each other. Then one night some other aliens landed and he had to go with them and leave me. I felt completely deserted in the dream and kept asking "why did you leave me daddy?" while looking at the spaceship leave the planet to never come back. Woke up soaked in tears and I honestly couldn't stop crying for a few minutes. It was crazy, I was well aware that it was just a dream but the deep feeling of abandonment was unshakeable. Oh well, I got over it, you mustn't let negative dreams get to you.
Harsh world? What sort of help are you looking for exactly?
