An excess of melatonin causes insomnia and nightmares
The natural supplement melatonin is designed to help your body sleep, and it’s generally considered safer than sleeping pills. That being said, if you take too much melatonin, adverse side effects such as excessive drowsiness, headaches, and dizziness can occur. Some users even report nightmares. But the worst possible thing is that when you overdose on melatonin, it can cause insomnia since the substance begins to confuse your brain.

Over-consumption of caffeine causes sound hallucinations
Many of us drink caffeinated beverages to provide that extra dose of energy and alertness on a daily basis, but weirdly enough, you can actually get high on caffeine. When you consume an insanely high amount of coffee, adrenaline receptors are triggered, and auditory hallucinations are one of the symptoms that can occur, as well as potential psychosis. Don’t drink more than four cups of coffee if you don’t want to lose your mind or start hearing things that aren’t there.

Essential oil overdose with aspirin

Wintergreen is naturally high in methyl salicylate, an ingredient in aspirin.
