in your dreams

In your dreams is a phrase often used when you want to describe something that isnt very likely to happen. By saying it is in your dreams, you are saying it is a way of fantasizing about something that you may want, hope and wish to happen but realistically it probably wont. Dreaming, like in daydreaming, is another way of seeing things from more of an unrealistic and hopeful way, rather than something that could really happen.
