Actually, you have about 4-5 dreams every night. But most people forget all of their dreams in the morning. If you are persistant in writing in your dream journal, than you might start being able to remember all of your dreams all the time ^.^ Every time you wake up in the middle of the night, write down your dreams if you remember them NO MATTER WHAT! Some people (including me, once) say to themselves "I will remember this in the morning, and I will write it down then". Well, you most likley won't.

Good luck and happy dreaming,
