Guys : Boy trouble! Plz help?

ok so im gonna make this as short as possible. basically, ive had 3 different dreams of the guy im supposed to marry. i know they were of him cuz im a strong christian and i honestly believe that God gave me those dreams. Anyways, in all 3 dreams the guy looked totally different, and i only got his name in the second dream, it was a really crazy name. And i met this guy (my sisters friends (who lives with us) brother) and so far ive seen him 3 times, and every time i saw him he looked at me the way the guy in my dreams would. This last time it was just me and my sisters friend at home. i was watching tv, when the doorbell rang. i got up to get the door, when i opened it, there he was (the real guy, this wasnt a dream, lets call him Mike). When he saw me, he seemed kinda taken back that i was the one answering the door. im not sure if he just felt awkward or if there was something more. He asked if his brother was home and i told him he was downstairs. He seemed kinda hesitant to come in, but did anyways. he made.his way downstairs and stayed down for a while. when he came back up to leave, he actually said "Cya" (usually this wouldnt happen, guys are usually rude to me). to be polite i said "bye". so is there anything unusual about this? was he just being nice? plz give me ur thoughts. PS. i thought i heard him catch his breath when i answered the door.
