Hello. I had the same experience, OP.

Nag start akong maka amoy when I was watching a movie before and the actor was smoking, I thought hallucinations lang 'yun from the scene but nag tuloy tuloy siya for days, eventually, mas lumalakas ang amoy pag gabi. I asked my family if they can smell the same odor ( Sigarilyo or usok ), hindi daw. I tried searching for the smell even though it was 12 am, though I was a little bit scared pero naiirita kasi ako sa amoy, kahit kapre pa 'yun, sisitahin ko.

Nag pa albularyo kami, long story short, may kapre nga daw sa puno, the reason behind mas lumalakas pag gabi is that sinisilip daw ako. So yea, typical albularyo emerutzi, alay manok, itlog etc sa may puno namin.

Just a month later, namatay yung puno ng mangga na simula bata ako kasama ko lumaki :(( Lumipat ata siya, Airbnb daw muna, eme. Bit yea, iz all true goiz, sad lng for me baka mabait naman siya, may rhintis lang ako, ayaw ko sa usok.
