Yeah, this exactly the right place

Welcome here Tlahti

Your first problem is completly normal. Everyone is like that and this is why this site is here, to train yourself to know when your dreaming and when your not.

And I had things like you too... Once I had a dream and then later on I read a book that I didn't know existed when I had the dream and I could remember a scene because that's what the dream was, exactly, every detail... No one (of what I know) can explain this but dreams somtimes show the future...

Also, same here, my dream recall is like a wave. Some days I remember so much other days barely nothing... Its a good thing that your dreams are realistic, it will help you. now all you have to do is learn how to remember my dreams. There are many tutorials for that

Good luck in your path to Controled LUcid Dream
