Help?

For the past few months I have had a recurring dream. In my dream I am looking for something in our apartment, or I am cleaning when I find a new room. Sometimes the new room is a complete surprise, and other times it seems like I knew it was there but I was too lazy to see what it was or what was inside of it. The room is always furnished. The furniture is usually pretty old, but always has a lot of character. The furniture isn't really my style, but in my dream I always think that Jerry would really like it (although I don't know if that is completely true in real life). Sometimes I find a whole collection of rooms. Sometimes there are even double chocolate chip cookies left in the room by the landlord.

These dreams are extremely pleasant. I wake up really excited only to really depressed about 10 seconds later when I remember it wasn't real.

Does anyone know what these dreams mean?! And why have I never had them up until a few months ago, and now I have them all the time?
