Hi there!

It's true that you need a good dream recall before you can really have lucid dreams. There's some things you should try if you can't remember any of your dreams. However, first you need to have enough sleep - 8 hours a day is quite a good amount.

When you're going to sleep at night, concentrate on your intention to remember your dreams in the morning. Tell yourself that "I will have dreams tonight. I will remember my dreams in the morning".

When you wake up you shouldn't get up immediately. Instead stay still in your bed for some minutes trying to remember your dreams. If you still can't recall anything, try concentrating on how you feel at the moment. Sometimes it might trigger you to remember the dream you just woke up from.

And the most important one is to have a dream journal where you write down everything you can remember in the morning. You need to write it immediately when you wake up, and you really need to write whatever you remember, no matter how unimportant it might feel. Keeping a dream journal will help you to improve your recall.

I hope this helps.
