To someone who has never come across this or utilised this really bueno stuff, give it a try. You will, right? 
So I came across this recording (and many others) while browsing youtube for meditation music and gave it a try just before sleep.
I really don’t have much to explain here, but the idea is that you are on a journey that takes place in your mind. A voice guides you and describes everything in detail and you visualise the events in your mind as you listen. For example the one I linked takes you to J.R.R. Tolkien’s fantasy world.
I feel like the recording and the visualisations I did seriously helped me sort out my thoughts and just recharged my mind. It’s funny because originally I didn’t go for it in hopes of getting an LD or improving dream recall.
My recall is bad nowadays and my dreams are usually not very vivid and usually blurry. I rarely get enough sleep. But that night my dreams were much more vivid and rich and my recall was somehow refreshed, since most of my adventures were still fresh in my mind after I woke up. I even had a moment of lucidity during one dream where I was fooling around with my fancy telekinetic powers and experimenting with human flight. 
I’m gonna continue using these and I genuinely recommend it to everyone! For us Middle-earth fans there’s also a recording for the shire and the elven haven in the same channel: youtube.com/user/TheHonestGuys/videos?view=0
