hey there. It takes me a long time to fall asleep too, but I have Lucid dreams. I think you should just start off by making sure you have good dreamcall, minium of 2 dreams remebred each night. You can also do reality checks. Those are when you perform some sort of test ( like putting your finger through yoru palm) periodly each day to test wheater you are in a dream, or are in real life.
