You can cleanse your house with 'Smudging'. It's a herbal mix that you set light to as a cleansing measure for your house. To reverse a hex, you can make a witches bottle, and yes, it's very effective! As for that psychic, I would take it with a pinch of salt! Literally! For starters, a psychic should not say that without proof, and second, remove all evil influences with salt. Sprinkle salt on your head, around the doors and on window ledges.
