hello mikey980 
welcome to LD4all
you should get your recall better before using methods to have LDs since as you said it’s a waste of time having a LD if you can’t remember it.
We do have a topic Sticky: the BIG remembering dreams topic part IV <— now on part 4 … everything you need to know inorder to improve your recall is in that topic https://community.ld4all.com/t/the-big-remembering-dreams-topic-part-iv/21934
the main points are …
- set the intention to remember your dreams! before going to sleep tell yourself you will dream and remember the dream!
- when you first awake … don’t move … just think and try to fish for the dream … see if any dream fragments are remembered … then think yourself forward/backward through the dream
- keep a dream journal
