I had a dream of a guy I don't even know?

There may be some quality that is lacking in your boyfriend that you wish he has but that this subconscious Michael has in abundance. It does not necessarily mean that you'll meet someone else. Though, that could happen. Michael is a common name, so it may not be a surprise that your mind chose that. However, who's to say some guy name Michael will enter your life. Just don't wait around for it.
