Is it normal to dream/ to have nightmares everyday???
I always dream that im flying (w/o wings) and chased by a group of people, sometimes i hide or i cannot control myself flying wherin i go up higher and higher outside the outerspace then burn or i will fall down fast and i'll wake up...
P.S. pls explain it to me if anyone knows what it means...
