Everyone has had a weird dream at one point or another in their life. Dreams can be downright strange and leave you wondering what on earth was going through your subconscious mind when you dreamed them. But what if your weird dreams were caused by something other than your overactive imagination? What if they were actually caused by a vitamin deficiency? Believe it or not, that’s a possibility! Vitamin D is known for its many benefits, including helping to promote good sleep quality. But ironically, vitamin D deficiency can also cause strange and vivid dreams. If you’re experiencing frequent weird dreams, it might be worth getting your vitamin D levels checked to see if you need to start supplementing with this nutrient.
