I had a weird dream this morning?? Please read full thing...?

Woke up at 9, then fell asleep again, where I had this weird dream. I seemed to be back at school in the dream (though I'm 24 and it wasn't actually my old school building in my dream but was meant to be if that makes sense?? lol). I was outside with a couple of people I went to school with and one of them said she saw a huge erfly. She then saw it again and managed to catch it. When she did, it looked like an exotic bird that perched on her finger. I was afraid to touch it. Then in the distance, I saw 2 leopards, so slowly I turned round to go round the corner, but saw another one. I tried to go past without it seeing me, but it did, snarled and looked ready to pounce. It chased me into the building. Once there, I realised that there were loads of animals and they were chasing the humans and turning them into zombies. There was a wee group of us left so I got everyone to run upstairs. Once there, I went ahead with someone else to find a hiding place.
