The dream you had at 10 in the morning, obviously, I don't think it is a sign. Generally, I dream of marrying my lover. From a psychological point of view, you have completely accepted your boyfriend in your heart, and you love him more and more. You think he is the one you can depend on for a lifetime.
As for dreaming that witnesses are friends and witches dress up, it is your subconscious dream that your love with your boyfriend will be disturbed by external things.
You can tell your boyfriend your dream. Maybe he will propose to you right away. I wish your real wedding will be held as soon as possible and I wish you happiness!
