hi seero
from what I know of dream interpretation when you dream of a house you are dreaming of your own mind. the attic is your superconscious and the basement is your subconscious. this person was telling you to stay out of your subconscious mind. so maybe it was your own fears of what you would find there if you were to explore. welcome to psych central. you will find we have several forums where you can post about your concerns and receive feedback from other members. you will get a lot of support here. again, welcome
