Daydreamer, this is a /love/ issue, as far as I see it, rather than a /personal/

Your comments about having a rational and emotive part aren't so much what seems different about you, it's your thinking of things as separate entities that is unusual. Your ability to distance yourself from your own thoughts is something I haven't encountered before. It could potentially make you a good writer.

About "Vanessa", I do think that you're relying on "her" as your Mode of reality, rather than a part of your reality. In other words, I do believe that you recognize her as not real/illusory, but have so long been int eh position of thinking about her/utilizing her as a tool that you're afraid, uncertain, or both of leaving "her" behind because the idea of experiencing life with her has been your routine.

As a psych student, I have to say that this is not a healthy thing. While there may be benefits to dreaming of communication and having "her" push you to doing things you believe that you should, they're not likely to be any better than simply rehearsing potential conversations with others and pushing yourself. I think that this imaginary projection adds a negative, though, which is the ease of the situation. This isn't to say that you'll always be afraid to approach others because you think of an imaginary friend, but that you've become comfortable with a certain way of communicating and thinking about social interaction. Real life interactions may be, and likely are, more complex, and it may be easy to wish to simply push them aside and stick with your false reality.
