what did this dream mean?

I'm not sure. But I come to realize that almost dreams have a subconcious or subliminal basis. What I mean is that dreams could be a manifestation of all the information that our brain receives through out the day because our conciousness can't process it all directly. For example there are many details and bits of information that we absorb throughout our life but we don't even realize that we acknowledged them until you dream it. You may have seen certain expressions on peoples faces that slip your concious attention but then later realize when you dream. Also deeply buried fears of yours can surface in dreams. I would advise you to be careful because I take dreams seriously. Be careful.

I don't know. Mybe you have a puzzle that is in your brain and you need to figure it out. Are you under any abnormal stress right now with your B/F?
