Question about Vitamin B12

So I was looking around my medicine cabinet because I wanted to see if I had anything like B6 or B12. I found a 151 Super Joint Formula by Nutrition Depot. I was wondering if this supplement had any effects on vivid dreams, I've already taken 2. I'll post pictures of the things and also write down the supplement facts.
