Do you ever wonder why you remember some dreams and others you can't recall at all? Well, here are some eye-opening facts about dreams that will answer that question and much more:

  • We have anywhere from 5-to-12 dreams each night. A study from the University of California found that we dream about every 90 minutes. And the average person has more than a 100,000 dreams in their lifetime.

  • You can control your dreams. How? Kelly Bulkeley wrote the book Dreamcatching and he recommends giving yourself a pep talk before you go to sleep. In other words, if you致e been having nightmares lately, try telling yourself something like this: 的f I have that dream again, I知 going to remember that it痴 not real. I don稚 have to be afraid.

  • They can help you learn. If you池e studying for a test, then sleeping will do more for your grade than pulling an all-nighter. Why? According to a study we found in the journal Current Biology, dreams are the brain痴 way of processing and remembering new information. But know this: if you want to get the most out of the process, don稚 fall asleep watching TV or listening to music. That痴 because background noise impacts the length and quality of our dreams.

  • If you want to remember your dreams, stay still after you wake up. Lauri Loewenberg wrote the book Dream On It. She says that stretching - or rolling over to hit snooze instantly switches your brain from dreaming to conscious thought. But, if you stay still, your brain has a chance to transfer all that dream information into your memory.
