"You may have acquired a cursed object, hence the reason the ring was left lying on the ground to begin with. I've read noteworthy literature that discusses how certain spirits energetically attach themselves to physical objects, manifesting their presence when a human comes into contact with the item. Visual distortions and anomalies of that nature are often caused by malevolent spirits that will grow increasingly hostile with the passing of time. I wouldn't be surprised if you start noticing the appearance of 'shadow people' in your bedroom while you're trying to sleep. That kind of thing is the explicit manifestation of the demonic. Ultimately, any evil spirit that hovers or aggrevates will do so to try and wear you down. Over time, with sleep deprivation, you can become mentally, physically, and emotionally exhausted, giving the spirit a chance to try to inhabit your body. Please get rid of the ring."
