dreams. they're one of the things that is unknown, to say the least. i mean it's something in the future and you don't plan for it. i'm talking about the dreams that you get in your sleep by the way, not your life goals or what you want in life etc.
anyway. yes. you don't really know what you're going to dream about when you go to sleep tonight. you can't really plan for it. sometimes you do wish that you dream a certain dream because of its nature. i mean, sometimes dreams can feel/be so real, you will feel it. you will wake up still having experiencing the effect. still feel exactly like how it makes you feel when you sleep. bliss. so each night you go to sleep you will hope that this kind of dream will reappear so you can feel it again. it's sad though. because that means you don't really have any happy things happening to you in real life, that you only hope to dream it.
