[No he's not being melodramatic, he's being honest here. Sure they just met, but this vision held a lot of meaning for him. A lot of deep meaning.]

...Maybe I'm wrong. But then I guess the reason I feel that way is there's a lot of things I don't know about him. We could be completely different people personality wise and part of me is afraid to meet him because of that. What if we don't get along or hate each other? I wish mom and Gohan told me more about him.
