if you cant remember your dreams well then if you havent already, start a dream journal. If you started a dream journal then, write your dreams down in more detail. It could seem unclear because you have trouble remembering it when you wake up. I had very vivid DILDs before but when i woke up i started to question if they were actually DILDs or just non lucid dreams. It could also have something to do with which REM cycle you are on. Try taking a multivitamin before sleep and see if that helps.
