Really weird/upsetting dream

Last night I had a dream that I went away to some school and I had friends with me. It took place in kind of like and "x-men" like world, most people had special abilities. During the day the area I was at had some huge attack. Almost like a terrorist attack. But I was teleported out of the area to some house I Arizona or something. I only had burns on my arms and no one in my family, or any of my friends were answering me. Then I woke up completely freaked out.
