Certainly some houses do seem to have a warm and happy atmosphere. Dds' both did - you instantly felt that this had been a happy home. Can't say the same for all the houses I've ever looked at my any means.
In some cultures belief in bad vibes is perfectly normal. A Swedish friend who used to live in Thailand had a similar expat friend who moved her family and Thai maid into a 'new' house. Maid was instantly wary, said, 'Madam, this very bad house, bad spirits here.' Of course 'Madam' pooh poohed it as superstitious nonsense, but a couple years later, after everything from illness to you-name-it had gone wrong for the family, they moved out. And lo and behold, from then on things rapidly improved.
Who knows? There are more things in heaven and earth, and all that...
