Falling within your dream is said to be a sign of anxiety and vulnerability. It can also symbolize a decline in your energy or status. Falling can sometimes be an omen of misfortune to come, or represent submission to the control of another in, for example, sexual intercourse. Dreams of falling often occur during times of upheaval or Changes of great magnitude in your life.
Its totally normal. Well its kinda hard to explain, but having that dream kinda means like your about to die, because if you dont wake up or move so you wont fall frm your dream, and you keep falling, it actually means your really dead. Thats why you move or jerk yourself to wake up. Yea kinda complicated. (:
Cause it gets so intense and the heart beat a lot or something like that
