BPOV
Edward and I were sitting calmly in biology when it happened. My head began pounding furiously. The lights suddenly seemed to get brighter and my vision began swirling. I wasn't breathing, my heart wasn't beating. I felt sick to an extreme.
EPOV
I was trying to pay attention. Banner was prattling on about something I had heard a thousand times, so I had redirected my concentration. I began to hear, not physically, an immovable presence. Another vampire. Alice should've seen this coming. Unless of course he had come from La Push. Filthy mongrels, they smelled hideously disgusting, and were always getting in the way. I wasn't sure what Bella saw in them.
And then my head started pounding. I hadn't had a headache in nearly eighty years, not since becoming a vampire, despicable creature that I am. The lights began to dim and my vision began swirling. I was breathing too quickly, my heart was actually beating. I felt sick to an extreme.

I opened my eyes again. I was feeling much better. But the room had changed somehow, I was not in the right seat, and it was so much more detailed. I could practically count the hairs on Mr. Banner's head, though he was on the other side of the room. My mouth was filled with a sour tasting substance. I quickly swallowed and more materialized.
Do I have to be sitting in this class? I heard Mike say. When I turned to look at him he wasn't moving his mouth. I'd much rather be with Bella. Damn she's hot. What the hell is Cullen staring at? I blinked and looked over to my right, to see Edward, and my eyes met a blank wall.
EPOV
I opened my eyes again. I could feel my pulse. It was physically impossible for me to have a pulse. I tried to listen for the vampire presence I had sensed, and couldn't hear anything. I felt blind and deaf. The lights were dimmer and I could only just see the other side of the classroom before it started to go blurry. Usually I could hear twenty-odd pulses, twenty-odd sets of lungs and twenty-odd thought conversations, but I could barely hear Banner anymore. I looked to my left to see Bella and saw Ben Cheeney, across the aisle, doodling on his book. I was in the wrong seat. I also wasn't thirsty anymore. I couldn't taste the venom in my mouth. I could however taste something minty in my mouth.

I looked to my left instead and froze. I was looking at myself. My brown curly hair, my confused expression. I inhaled sharply and regretted it. I smelled delicious. It was an intoxicating scent. My mouth filled up with the sour substance twice as quickly as I smelled me, felt the blood rushing through the body beside me. I held my breath, trying to control the sudden need to kill I felt.
EPOVI could feel something tickling my neck. I raised my hand to it and felt long, soft locks of hair. I heard a sharp inhale from my right and looked up to see my own face staring back at me. But that wasn't the worst part. I looked thirsty, excited. I looked down at my hands and saw Bella's bracelet on my wrist. The shiny, black binder in front of me reflected a warped picture of Bella and my mouth fell open. This was extremely dangerous. Somehow Bella and I had switched bodies. Now, the entire family was at risk, not to mention me, or rather, the body I inhabited. Bella usually smelled so good to me, it was hard to resist her at all, after seven decades of control practice. If Bella was in my body then she had literally had only minutes. I was sure I was going to die. Killed by my own body. How practically ironic.

I suddenly realised what must be happening, though my brain wasn't sure I could accept it. Edward and I had switched bodies. I was positive I was going to kill him, or rather, me. I smelled so intoxicatingly delicious. I could hear his/my sharp breaths. I could hear everyone's breathing, everyone's pulses, everyone's thoughts. I had to move, before I did something really ridiculous. I gripped my arms, trying to hold myself together and stood up.
What the hell is Cullen doing? Mike.
What is everyone looking at? Ben.
I don't understand. Would Banner explain it to me later? Angela.
"Mr Cullen?" Banner asked.
"I feel...sick." I made up quickly, and left the room.
Wow he moved fast. I stood outside in the pouring rain and felt so much better. The scent had disappeared. It was easier to breathe, to think. I had to find Alice, or Jasper. I couldn't go back into that biology class. I knew Alice had government class now, so I headed towards the building. Suddenly I could hear her.
Edward? Why do I see you bursting into my government class? I'll be out in a few seconds.
I looked around to find her but I couldn't.
"It must be her mind." I was breathing heavily. I could hear every drop of water as it hit the pavement and me, I could see them all falling in perfect clarity. It was frightening. I could also hear something else, a nagging, presence in the back of my mind.
"Edward?" Alice asked. She came over to me. I looked around for Edward as well, until I realised she meant me.
"No, Alice. It's me Bella." I said, sitting down on the pavement.
I'm confused.
