Exercisings effect on dream recall

[chic]

I'm curious about what kind of effect exercising and dieting have on dream recall? Personally, I go to the gym every morning around 4:30 am and do weight training, which lasts for about an hour and a half. My diet is high in protein, low in saturated fat, and I consume a good amount of vegetables and fruits. Generally, I have an inconsistent dream recall, and I'm not sure if exercising and my diet may be the cause of it. Also, after reading up on how vitamin b6 can help you have vivid dreams, I took some last night. Although they had no effect on my dreams (I had no dream recall this morning), I did have one of the best work outs I've had in quite some time, plus I was in an amazingly good mood all morning... Coincidence or was it the b6? thanks!
