Any idea?

The past few weeks I’ve been able to smell pictures of items. Or if I’m watching TV and see a soda, food item, even some colors and random items, i can smell them. I can’t really explain it and it’s sort of like phantom smells. I’ll notice someone’s mouth on tv and can smell either funky breath or sometimes it’s more like dull toothpaste. I can smell the oil on skin.

I know, this sounds insane and someone will say I need mental help but I assure you, I’m fine. I did have Covid a few months ago.. I’m wondering if it’s an after Covid symptom. I’ve read others mention being able to smell or taste colors but didn’t think I’d ever do this.
