Unidentifiable smell
 

Lately, I've been smelling this weird rotting scent wherever I go. The smell itself only appears briefly and then disappears. I've looked around for any rotten food or dead mice/squirrels that may have died in the walls of my house, but I've found nothing so far.

I think it might be a spirit. Not sure if it's a demon because I haven't noticed any sudden intense "negativity" around my dad and I. Though i have been wrong before.

What do you think it may be? And what should I do?

I think the first thing I would do is smudge the bejeezus out of my house with a sage stick. I'd get the closets, corners, and drawers - and take it from there.

well you also wrote today that you are having dreams of an evil cult that wants to sacrifice you to their god & steal your soul, which involves being mutilated or deformed a little. So i think God is making you smell the rotting flesh to remind you of that cult. It could be a religion that wants to recruit you. Something your friends are into or something?

Anyway the smell is a direct warning from the Angel of God & is not an evil entity hanging around. LOL

Your Guardian Angel would never allow such an entity to exist around you
