Dream About Escaping From Knife Wielding Girl

My family was on vacation in Thailand (i am Thai and have been to Thailand). We were in this wooden condo with multiple floors. My family slept on the first floor and I slept on the second. Upstairs was a huge room, pretty empty, and circular. There is a girl with a knife who is standing creepily and tries to stab and shoot me. I don't really remember how it happened, but this girl Sarah tied me up to a chair, turned the lights off, and tried to kill me. The walls started spinning around like an MRI, and it was so terrifying. I somehow managed to escape and tied up Sarah instead. I broke the power box that allowed the walls to stop spinning and I left her there to die. I went downstairs to see my family putting their shoes on. I think they're going to some tourist sightseeing trip, so I put my shoes on to. While i'm putting on my shoes, my family leaves. I quickly finish and run outside, only to see they're not going on a sightseeing trip but playing volleyball with my family friend. I go back inside and I am constantly scared and paranoid Sarah will escape and come to kill me.
