You geel a strange tug as you reflexively lift your hands, and when you open your eyes, you see that a rectangle of earth had pushed it's way up from beneath the asphalt. It was abput five feet high, coming up to about your neck. More than high enough to block the icy blue beams that hoodie girl was shooting at you. You look over and see that she is scowling. "You tried to kill me!" You yell indignantly. You then remember that according to yur dream, LOTS of people would be trying to kill you. You suddenly feel the urge to kill the woman now staring you down from across the road.
You kick your wall of earth towards her and it goes flying across the ground, tearing up the road as it goes. You reach for the earth with your mind to your surprise, find it! You feel the presence of the huge turning spgere beneath you, feel the enormity of it. Its almost too much for you to comprehend, but you are snapped back into the present, when hoodie girl hits your arm with a ball of stinging cold energy. You reach with your ming and pull up a boylder if earth about the size of a small car and launch it at her, but she dreezes he air in front of it, completely stopping it mid-air.
"You're pretty good" she calls to you grudgingly "but you won't beat me."
"We'll see about that" you say back.
You raise your hand as if to pull up another boulder in front of you, but you pull it up behind her. Hoode girls sees that you left yourself wide open to an attack gathers some more icy energy, ready to spear you, but before she can, the boulder slams into her with a thick CRACK.
She falls to the ground unconcious. Still holding the boulder up, you walk over and check her pulse. She's out cold, but not dead. The urge to kill her is really strong, but you have a lot of questions that she might be able to answer.

Don't kill her! What are you? Insane?
