In my dreams I'm always walking about different unique rooms inside a beautiful house. Some rooms small some big but all beautiful. Why?

I think you are inquisitive and have an exploratory mind. That is what you are doing, you know, "exploring" each room of each house. Notice how you describe them; beautiful, unique, big, little, different, etc. You don't like being bored, so you keep hopping around, from one thing to another, "pictured as houses" in your dreams. Houses are just Symbols for the activities you would enjoy exploring.

Idk dreams are weird af, in fact I had a dream that I stole some gummy worms from my grandmas fridge and ran off into the bushes with them then i came out of the bushes as a horse, after that I ran through a forest and fell in love with a random Asian dude
