How do I tell if my dreams are the same ones or different ones?

Sometimes at night I don't wake up, or don't remember waking up. I can usually remember some of my dreams though. Sometimes I remember several things happening that seem unrelated. Would those be separate dreams? I'm not sure if it is just one topic that has run into another in the Same dream.

I'm trying to keep a Journal because my dream recall has been fading for 2 years and I have wanted to get back into the practice of LDing. I just am having trouble categorizing these as one or multiples.


A bit if history of me:

I HAVE had a LD before. One on my own before I knew what a LD was. I own a headset/visor blinky-thing by Zygon that has a CD called lucid dreaming. It has been successful in inducing only 3 lucid dreams in the past for me. I used to use it almost daily for at least a year.

So 4 total where I was aware of dreaming and could willingly change the backgrounds my dreams took place in and glide somewhat (not fly though)

I have recently been using Brainwave Synchronizer along with I-Doser (Lucid) to help me calm before bed and to help induce WILDs, etc. It has been helping tremendously! I recomend these highly to help. I have had a LD before so I kind of know the state I want to put my mind in to get another one and these work for that.

I was so close last night, I was aware I was dreaming and it faded so fast. I tried to spin and hand-look as recommended here but nothing worked and I got kicked from it after a few minutes.

I used to be able to recall almost 4 dreams a night without writing them down. They were always VERY vivid. My memory has waned (sp?) sadly to 0-1 and for almost a week now I've been trying to make that more.
