Soya Milk?

Hi, I was wondering if anyone here has noticed any more vivid dreams after drinking Soya Milk? I've been able to have lucid dreams pretty often for a year or two, and I've also been drinking Soya Milk (as a main milk source-still drink normal milk occasionally but mainly Soya) for about that amount of time. I don't know if it has helped me personally, but I've just noticed on the carton that it has lots of B vitamins in it- B2, B12 and Folic acid...not sure if B2 does anything but I've heard B12 and folic acid are good for vivid dreams.

I checked the normal milk (semi-skimmed) bottle and it has B12 in it, but about half as much as in the Soya milk...there is no B2 or folic acid in it either.

So I was just wondering if anyone has noticed any effects from drinking Soya milk? I have noticed more vivid dreams in the past year but it could just be a coincidence. Any thoughts?
