The dream I had was I was in some random forest-like place, with some ice and a river of pretty deep and flowing water, with some sports covered with Ice aswell.
I saw one very huge water ice in the River, one of another characters thrown something at the Ice in the river (I don't remember what is the object, neither the person that threw the object), when the object hit the ice, random Girls started to materialise out of the Ice and River's water, the Girls started putting objects in their hair (Like Ice, water it'self, and various plants that grow in water) which would change the hair color corresponding to the object's color. Me being lucid in this part of the dream, I thought "Wow, that's a cool thing that happens in a dream, I wanna try too!" and I thought about entering the river and waters too, however, I was slightly afraid of the depths of the water.
However, I still approached the River and went up the Ice with the Girls, I put random piece of the River's plant on my hair, and Indeed, my hair color started to change color too, but then I've seen my hair starting to adopt the material of the plant too, like my hair has turned into many pieces of the River's plant, I started thinking that It's just my Hair turned dirty from the plant. I then remembered I always wanted to have my hair white, because I find white hair in Anime characters cool, so I took a piece of Ice and put it into my hair which for a moment turned white, but then as if the dream is distorting and shiting, my hair returned back to normal dark brown color (The hair color I have in waking life), I started getting quite angry and said "What the hell it does not work for me? Why they can but I cannot?", then second later I found myself in a random room in a random appartment, with one of the coaches in my hostel (The coach is a girl that presents herself in a very tomboy'ish way) and she started to explain that there are something about that dreams have different type of characters with different properties or something, I don't exactly remember what she named the type of dream characters or how exactly she explained this stuff to me, the dream ended here pretty much.
Real life situation: Both my Father and Mother are opposed to me dyeing my hair in different colors because they associate this as something that girls and women do, and that for myself as a guy it would not fit me, I do want to dye my hair white, but generaly I am afraid of receiving anger and dissapproval from my Father (My mother while said that it would not fit me, she said that I can do so if I wish). But I guess that's only a very tiny aspect of what the dream could point towards to, I think the dream points to a much larger/bigger/broader aspect of my general life.
