My house is for sale, and I want it to sell soon, and I have a friend who does not even know the subject "lucid dream" right and he told me that I can affect reality with lucid dreaming.

How so? This confused my head, I know that's only a dream ..

He told me to go into a lucid dream, and then modify the dream,and imagine myself in the body of someone wanting to buy the house and self affirming "I want this house"
he said that it works.

But for me this is pure fantasy, my friend would be a little crazy?
