You look for a new boyfriend.
The simplest explanation would be that the dreamer's boyfriend was in the garage, talking with someone else while the dreamer was asleep. Sounds from other rooms or from outside often affect a sleeper's dreams. Otherwise, if the dreamer thinks about the boyfriend a lot, it would not be surprising to dream of him. A conversation in the garage would not have any special significance in a dream.
My boyfriend in handsome and he thinks I'm beautiful
Because he probably is! because he thinks its ridiculous and hes probably thinks ur jealous and that amuses him
If you yourself are a guy then she might be talking about you. Is this fictional boyfriend of hers sweet and loving? Maybe she thinks your like that and wants you to ask her out.
when he looks at someone really good looking and he thinks nah your better. i like your nipple tassles
Find another boyfriend.
You won't win your girl back by talking down her current boyfriend. Hopefully she finds out about him early on and doesn't get hurt too badly. Sorry, but for now, she is with someone else.
Because he feels like your to good for him and he thinks that you would easily want to leave him for someone else
It either means that: -He still kind of likes you but isn't sure yet -He thinks you're fun talking to but he doesn't want ot be seen talking to you -He's bored and wanted to talk to you online -He still really DOES like you but doesn't want everyone to know Hope I helped :D
Start looking for a new boyfriend.
Prove to him that you aren't.
That depends on why and what your were talking to her about.
