I had a scary dream tonight and I want to know what it means.?

[BriannaOstrom]

I am a college student and my dream started out at my old high school. I started to talk to her and I noticed that my old counseler no longer worked there so I asked he what happened. My friends mother told me that my counseler had a witch for a sister and then she began showing me all of these cracks and holes in the walls that supposedly where caused by the witch. ... then I had another scary dream the same night. I was with my Dad back home and me and him went on a car ride around town and he began rambling on about this new light that they have next to the football field and how it was a waist of money and he said something like stupid bikers which puzzled me... but anyway we turned onto the next street and it was extremely foggy and the only light was coming from that stupid one by the football field I looked along my side of the rode where our community park is and there where these mean dogs eating what looked like human remains and then I don't know why but my dad pulled over to let someone in to give them in a ride. As the visitor was in the front seat I couldn't help but notice his scary long fingers and it's oval like head this had a resemblance to the aliens you see on t.v. but yet it was still very unique. What does this dream mean and why did I have it?
