Beginner, starting from scratch and trying to improve recall

Since starting trying I have had 3 nights in a row where I've remembered my dreams, and I've really thrilled with that. This is compared to my usual recall of medium detail maybe once or twice a month.

However, every time I manage it my memory is so hazy - I can barely recall a line's worth of text on the dream... How would I best improve this? Is it just something that will happen over time?

The method I have used so far is repeating that I will remember my dreams in my head as I'm going to sleep, also the last 2 nights I have tried saying I will remember them in more vivid detail but that hasn't happened. I have also tried naming my subconscious and asking it to help me remember.

Thanks.

have you tried WBTB? It is a useful method for LD induction but you can also use it to improve recall. It is basically when you set an alarm clock to wake you up after about 5-6 hours of sleep. This should wake you up during rem-sleep. At this point write down anything you remember about the dream, if you can't remember the dream, don't worry, you will be going back to sleep soon so you have a scond chance :)
Stay awake for 15-60 minutes, read about LDing and set your intent to remember your dreams.
When you go back to sleep set you tell yourself that you will have vivid, memorable dreams etc (like you have been doing) and fall asleep.
As soon as you wake up in the morning play dead. Do not move or open your eyes try to remember what you were just dreaming about - do not think about anything else. If you can't remember the dream think about how you are feeling, why are you feeling like this. Even the smallest detail is worth recording.
Good luck

Wow.

I just inadvertantly did WBTB - I woke up after about that amount of time because I needed the toilet and I had a very vivid recollection of what I had been dreaming. I then went back to bed and dreamt again, and again remembered it vividly.

However, I doubt it will be practical for me to be doing this regularly, what with university and not wanting to be tired during the day etc. Should doing it occasionally improve my recall at times when I don't do it do you think?

I also have university on a daily basis and am rarely tired during the day after WBTB. On, busier days, or days that I have to get up early in the morning I usually just set the alarm to wake me up, write down my dream and go straight back to sleep.
I save the full WBTB (staying up for 60minutes) for weekends, days off or days when I don't have to get up early and can sleep-in.
If you find that you are too busy with uni, it might be best to practice WBTB when your lifestyle is less hectic.
