Hey How have you been? I'm not one to believe in the supernatural (nor Freudian symbolism much) so I think a dream is just a dream. Maybe you have an unconscious doubt about your friend? Oops, sounds a little Freudian
To me it's just...a...dream But I hope you won't let it bother you too much.
I'm sure one of the resident dream interpreters will give you a more interesting answer.
