Multiple Lucids creating Problem!!

Hey everyone,
Well lately i have just emerged from my black and white lucid dreaming era and fallen into having multiple Lucid dreams a night. Its really great, but as i get multiple Lucid Dreams my dream control falters. Last night I tryed as i could to fly but i always fell smack on my, i wasnt able to summon anything or much at all except for sit around and hang out with DC's. All i could do is control myself and some DC's. I really hate nat being able to do much because all my Dreams are going to waste.
Can someone please help me get my Dream control back to how it used to be??
