What happens to me? Someone help ?

Last summer i went to Mexico by myself. I'm 17. The first night I spent there was weird. I woke up at 2 a.m. All freaked out. I was like yelling "where am I! , where am I!" and i couldn't control myself. I was breathing right also. An I was so freaked out that I was like running on my bed. Then all of a sudden I calmed down and knew where I was. What happened? Did I have like a anxiety or panic attack. I was not having a nightmare
