Dream had found you in an abandoned AU. He sensed your negativity and got there before his brother, Nightmare, could. Ever since then, you've been best friends! Even going as far as helping Dream fight his brother and his gang. You were so happy and Dream was happy that you were happy!

What neither of you expected to happen though was during a fight with Nightmare, he released a burst of negativity, making Dream and his aura weak. It was right there and then that you realized that you were not happy but in fact tired. Tired of fighting constantly with little to no breaks. Your own goals faded from your mind helping Dream fight. Dream had been using his aura to keep you happy so that he could become more powerful.
