I ve been smelling things that aren t really there lately, like cigarette smoke, the smell of weed and perfume. They haven t been really strong but strong enough for me to know what the smells are. Nobody smokes cigarettes or weed in my house so it can t be that and I ve never smoked before either so it s not me. I don t have any more of the perfume I smell, and I haven t had any of it for at least 3 years, before I moved houses so it can t be that either. I can also taste the smoke in my mouth sometimes (it tastes similar to how it would smell) this started after i heard about phantom smells. what could this be? thanks
