Dream of father, mother

In the dream I had, I was standing inside an airport waiting for my mother. However, what happens next is very confusing. I am suddenly knocked out and I don't know how I was knocked out. In the dream, I do wake up, but I am in a very strange place. It turns out to be my father's house and I am greeted by my father and half-siblings. Now, I never met any of them so I look very confused and a little scared in the dream while my father and half-siblings are all happy to see me.
