What is the efficacy of cleansing my house with sage to ward off unwanted spirits or ghosts?

Lately, I’ve been feeling uneasy in my home, almost like there’s some heavy or unfamiliar presence around. I’ve heard people say that burning sage helps ward off unwanted spirits and clears negativity, but I’m not sure if it actually works or if it’s just belief. When I tried it once, I couldn’t tell any real difference. How effective is sage really for cleansing my house and protecting it from negative or unseen energies?
