Do you only get residual energy from someone or something that used to live in that space and has now passed or can you get it from someone who is there most of the time but has been away from this place for say six months and could be thinking about their home.
Well it's all a load of rubbish I'm sorry to say but if you insist in believing in it then you can just make up whatever you want about it and you will not be "wrong".
