Does imagining alot help you with LD'ing/Dream vividness? Since i'm usually ALWAYS inspired I just imagine how my movie would roll , and most of my dreams are REALLY vivid. So I was just wondering , is this the reason? if it is , could I somehow use it to help me have a lucid dream?

Imagining on it's own, won't or shouldn't yield a lucid. If it could, we would fall asleep or lucid every time we drifted off into daydreams. You will need to couple that with another method on here. If you just try to lay down and imagine a place to lucid in, you won't. On it's own, not going to get you anywhere. But yes, having a decent imagination lets you get into dreams easier and the quality of you dreams will be greater too.

It can help with dream control, because if you're used to visualization, you can (obviously) visualize things in the dream easier. Dream vividness may be affected by it, but IMO it's more of a physical/biological thing - your ability to recall is based on your memory, and not how much you can imagine things. I'm saying this because I'm the same way - I'm always daydreaming; I do it up to three hours a day when I'm being unproductive or bored, but my dreams aren't always vivid. That's just an anecdote though; others will have their own experiences. As for inducing lucidity, probably not. Lucidity is caused by consciousness or awareness of what's around you, and stuff like that, so there isn't much of a visualization aspect to it.

I did this today, my visualization turned to a dream but I did not become lucid. (it was 5.30 am, thats probably why it happend)
