I haven't dedicated time to rituals of any kind for a long time, but it is true that energies exist and cohabit with us, people who used to live in the same place could have been a breeding ground for bad energies and this remains impregnated in every wall of that place, this is why it is good to move the energies, there is no perfect method, you just have to do it, some music with a good frequency, incense, prayers, fragrances, whatever can be of help.
