Dreams fusing together in my memory

I'm starting to get back my dream recall, but when I'm trying to remember the whole dream sometimes I confuse myself if one part of the dream I actually had last night or a long time ago.

For example: last night I had a dream where I was in a school and I was trying to remember if I went into this big locker room area but then I remembered that wasn't actually last night, I had the dream with the locker room a long time ago and I had a different dream last night. Any tricks to stop this from happening? The chronological order in my memories is getting messed up. :shock:

Write your dreams down every morning and read them during a day or before going to bed. You will then distinguish all the dreams.

Hitokage gave a good suggestion, write dreams to your DJ as soon as you wake up and re-read through the day/before going to bed. Additionally doing some memory practice can help too, which can also help with recall, like remembering events of whole day before going to sleep. :)
