(before i start i wanna say the way my world is in the beginning is my world in my mind)

ok so i wake up and im in my 幻想 world, it looks like, gray skay, green feild as far as the eye can see, purple paper flowers, and one black pond in the center, ok so i wake up and im in a black n' white omish dress in my world holding a black rose, and im happy and feel good inside, so i lay there holding my black rose, so i go inside the black pond, i come out and im trenched in blood and everything is now snow, so i try to dig for the 草 but its just snow, im freazing clod, wet, and trenched in blood, so i know im going to die so i lay on the snow holding my black rose geting ready to die, and then i kept hearing Duncan's voice so i try and follow it, but i cant find him, so i lay there and die and closed my eyes, then someone tried to pick me up so i opened my eyes and it was Duncan, he told me to go to sleep and it will be all over, so i 说 okay, then he picked me up, and when i woke up i was at his house on the couch, so i 说 what happend and he told me i was trapped in my own world, so i 说 how did u get there, he 说 i went inside your voice, and i 说 thank you, and we fell asleep on the 长椅, 沙发 together, when i woke up he was gone, so i got up and screamed for him, and hes on the floor dead, so i screamed and brought him to my world and we died together in the snow with that one black rose,

i woke up screaming, can anyone tell my what this means, because some dreams are signs, someone please tell me it scared the shit outa me
