I had a dream that it was our wedding day and nothing was done, I even had to shave his beard!?

I think you are trying to do too much yourself, and are not trusting anyone to help. If your dream told you that you had to shave your fiances beard, then it sounds like you are worrying about his participation. Are you trusting people to take care of certain details? Is your fiance playing an active part in wedding planning? Are those particular details that you dreamt about, being taken care of by someone else? If you think about it, the guest book, is a very minor detail. I don't know anyone would notice if it was missing. As for the cake, probably wouldn't notice that either, especially if your having a desert with the meal. Some weddings make the cake cutting a centre piece of the reception, others, its no big deal. The only thing that matters on that day, is you-your groom- and the person who is marrying you. THAT'S what its all about.
