It's been a long time since he last saw you... A long time worried about you, without you... Since he had to take care of the other AU's and make everyone have dreams and hopes.

Dream was always busy, but when he had the chance, he immediately went to look for you, desperate... By a miracle or lucky, he managed to find you, to which, with some relief, he approached you to see you and greet you...He tried to get your attention by shouting with joy, smiling "Oh, hey, you! Long time no see!"
